Answer: It is b
Explanation:
The lack of protein in the body will result in a lack of energy in the body. Hence, option B is correct.
What is protein?Proteins are created from a variety of amino acid building blocks. Our body needs dietary protein to supply amino acids for the growth and upkeep of our cells and tissues. As we become older, our dietary needs for protein change.
Proteins are made up of many different amino acids that are joined together. Both plants and animals have a lot of these 20 different amino acid building blocks. Each protein has a unique ratio and arrangement of the 300 or more amino acids that make up a typical protein.
Our body is made up of thousands of different proteins, each of which has a specific function. They contribute to the structural components of our cells and tissues, along with the countless enzymes, hormones, and active proteins produced by immune cells.

A bullet is fired horizontally at 343 m/s from the top of a building where height is 37.3 m. The built will be
in flight for seconds
Answer:
Explanation:
A classic projectile motion question. Horizontal motion does not matter whatsoever in the context of this equation as we are looking at the vertical component of velocity only. Since the question states that it is fired horizontally, there is no vertical component of velocity. Thus, v0y = 0.
Assuming the projectile is on the Earth, we can use the free-fall acceleration, 9.8 m/s^2.
The question gives us Δy, which is 37.3m.
Using the second kinematics equation, Δy = v0t + (at^2)/2, we can substitute in the values.
37.3 = 0 + 0.5(9.8)t^2
37.3 = 4.9t^2
7.61224489796 = t^2
t = 2.75902970226 seconds.

a student redid the experiment of mixing room temperture water
Answer:what do you need to know
Explanation:
What is the average velocity of a car traveling South on a straight road for two hours returns to the starting point after three hours.
The average velocity of the car traveling south and later returned to the starting point is 0.
Average velocity is defined as the change in displacement per change in the time of motion.
Average velocity is calculated as follows;
[tex]v = \frac{\Delta x}{\Delta t} = \frac{x_2 - x_1}{t}[/tex]
Let the initial displacement of the car, x₁ = 20 m
Let the final displacement of the car, x₂ = 20 m (since the car returned to the starting point).
The average velocity is calculated as;
[tex]v = \frac{x_2 - x_1}{t} = \frac{20 - 20}{5} = 0[/tex]
Thus, the average velocity of the car traveling south and later returned to the starting point is 0.

Write down the relation between force pressure and area
Answer:
Answer: Pressure is directly proportional to force and inversely proportional to area.
Explanation: Pressure is defined as the ratio of force applied to the area of cross section.
Mathematically,
P=\frac{F}{A}P=
A
F
where,
P = Pressure
F = Force applied
A = Area of cross-section
from above it is visible that pressure is directly proportional to the force applied which means that if force increases, pressure increases. It is also inversely proportional to the area of cross-section. So, when area of cross-section increases, pressure decreases.
The units of pressure are N/m^2N/m

Two astronauts are playing catch in a zero gravitational field. Astronaut 1 of mass m1 is initially moving to the right with speed v1 . Astronaut 2 of mass m2 is initially moving to the right with speed v2>v1 . Astronaut 1 throws a ball of mass m with speed u relative to herself in a direction opposite to her motion. Astronaut 2 catches the ball. The final speed of astronaut 1 is vf,1 and the final speed of astronaut 2 is vf,2 .What is the speed vf,1 of astronaut 1 after throwing the ball?
The final velocity ([tex]v_1_f[/tex]) of the first astronaut will be greater than the final velocity of the second astronaut ([tex]v_2_f[/tex]) to ensure that the total initial momentum of both astronauts is equal to the total final momentum of both astronauts after throwing the ball.
The given parameters;
Mass of the first astronaut, = m₁Mass of the second astronaut, = m₂Initial velocity of the first astronaut, = v₁Initial velocity of the second astronaut, = v₂ > v₁Mass of the ball, = mSpeed of the ball, = uFinal velocity of the first astronaut, = [tex]v_f_1[/tex]Final velocity of the second astronaut, = [tex]v_f_2[/tex]The final velocity of the first astronaut relative to the second astronaut after throwing the ball is determined by applying the principle of conservation of linear momentum.

What is the car's acceleration
Answer:
The acceleration of the car was one meter per second squared.
Explanation:
We can use one of the kinematic equations:
[tex]\displaystyle v_f = v_i + at[/tex]
Where v_f is the final velocity, v_i is the initial velocity, a is the acceleration, and t is the time (in seconds).
The final velocity is 40 m/s, the initial velocity is 35 m/s, and the time is 5 s. Substitute and solve for a:
[tex]\displaystyle \begin{aligned}(40 \text{ m/s}) &= (35 \text{ m/s}) + a(5\text{ s}) \\ \\ 5 \text{ m/s} &= a(5\text{ s}) \\ \\ a &= 1\text{ m/s$^2$} \end{aligned}[/tex]
In conclusion, the acceleration of the car was one meter per second squared.
A penny is made of the element zinc plated with the element copper; a nickel is made of a mixture of the elements nickel and copper. Some isotopes of various elements are listed below by their atomic number and mass number. Use the periodic table on p. 131 to identify which atoms you would expect to find in the penny, which you would expect to find in the nickel, which you would expect to find in both, and which you would expect to find in neither coin.
Answer: We need the referenced table to discern which isotopes are likely to be found. But there is still an interesting piece of information.
Explanation:
An interesting story behind the US penny. It has been around since 1787 and consisted of primarily a copper, or copper-plated coin. In 1982 the design was changed, due to the high price of copper. A zinc core was copper plated to have the same appearance, but less expensive composition. If one of these pennies is slightly filed to expose the zinc, it can be placed in a strong acid that will react with and dissolve the zinc core. Fun, but a waste of money.

Be affectionate. Most girls love getting showered with affection and compliments from a guy they care about. Some girls can be insecure, and love being reassured a lot. To be affectionate, just give her a gentle touch, put your arm around her, hold her hand, or do whatever you can do to give her a little bit of physical touch. This doesn't mean you have to use everything you have on her, pick the right moments to let her know you care and it'll mean a lot more than having your arm around her for four hours.DO YOU KNOW SHE LIKE YOU?Look for open body language. When a girl likes you, she will face in your direction. If a girl has her torso turned towards you in an open manner, this means that she is confident talking with you. If she has a closed body position, namely crossed arms or legs, she may be shy or nervous to talk to you or she may simply be creating a barrier to signal that she is uninterested.[1]When she is sitting with her legs crossed, watch her feet. If they are pointed towards you, it might mean that she likes you and wants to get closer to you.[2]Generally speaking, a girl will stand closer to you and will have more relaxed body language if she feels comfortable around you — for example, she'll have relaxed shoulders and she won't cross her arms, But, everyone's personality and cultural upbringing are different, so don't take it as a sign she's not into you if this isn't the case.[3]Two metal spheres are suspended on wires so that they hang next to each other, just touching.

What is the relationship between the distance from the Sun and the orbital period?
P^3=a^2
P^2=Gm
P^2=a^3
T^2=P^3
Answer:
Kepler's third law - shows the relationship between the period of an objects orbit and the average distance that it is from the thing it orbits. This can be used (in its general form) for anything naturally orbiting around any other thing.
Formula: P2=ka3 where:
P = period of the orbit, measured in units of time
a = average distance of the object, measured in units of distance
k = constant, which has various values depending upon what the situation is, who P and a are measured.
This is the general form of the formula, so obviously you need at least two of the quantities to find the third. "k" is the trickiest thing since it depends upon the objects that are involved and how you measure "P" and "a". Since "P" can be measured in any unit of time (seconds, days, years, etc), and "a" can be measured in any unit of distance (meters, km, AU), the value of "k" can be quite diverse from one system to another.
There is a simplified version of this law: P2 = a3 where:
The object must be orbiting the Sun
P = period of the orbit in years
a = average distance of the object from the Sun in AU
This version is much more simple, since it has "k" = 1, so it is ignored when those units of measure are used.
