A student is given a red and a blue liquid. The two samples of liquids are
heated in identical beakers over identical Bunsen burners. The red liquid
shows a dramatically faster increase in temperature. Which of these is the
most likely explanation for this? *
O A) The red liquid has a greater mass.
O B) The blue liquid has a smaller mass.
O C) The red liquid has a greater specific heat.
OD) The red liquid has a smaller specific heat
When a substance has smaller specific heat it needs less heat to shows changes in it hence making the option D correct.
Answer:
option D) the red liquid has a smaller specific heat

Explanation:
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.
Answer:
in the penny Cooper(Cu),un the nickel nickel(Ni),in both Cooper(Cu)

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.
According to this graph, the acceleration
is approximately:
Velocity (m/s)
1 2 3 4
Time t(s)
5
A. 4 m/s2
B. 2 m/s2
C. 1 m/s2
D. 3 m/s2
The acceleration is approximately 4 m/s². Therefore, the correct answer is:
A. 4 m/s²
To determine the acceleration from the graph, we need to look at how the velocity changes over time. Acceleration is defined as the rate of change of velocity with respect to time. In other words, it is the slope of the velocity-time graph.
Looking at the graph, we can see that the velocity changes from 0 m/s to 4 m/s over a time interval of 2 seconds. To calculate the acceleration, we use the formula:
Acceleration (a) = Change in velocity / Change in time
Acceleration (a) = (4 m/s - 0 m/s) / (2 s) = 4 m/s²
So, the acceleration is approximately 4 m/s². Therefore, the correct answer is:
A. 4 m/s²

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]Why is the temperature of a normal healthy old man is less than that of a normal healthy young man?
Answer:
Normal body temperature does not change much with aging. But as you get older, it becomes harder for your body to control its temperature. A decrease in the amount of fat below the skin makes it harder to stay warm.

If you push on a cart, the force of friction will slow it down. Friction is the conversion of kinetic energy to __________ .
Answer:thermal energy
Explanation:The friction converts kinetic energy to thermal energy (heat). When two objects are in contact, friction will act with these two objects so this...
Answer:
Heat
Explanation:
Friction always slows a moving object down. ... Friction can be a useful force because it prevents our shoes slipping on the pavement when we walk and stops car tyres skidding on the road. When you walk, friction is caused between the tread on shoes and the ground. This friction acts to grip the ground and prevent sliding.

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 force of 360 N [East] was applied by a student on a box with a mass of 50 kg.
What is the acceleration of the box if a frictional force of 340 N acts in the
opposite direction?
F = F⁰ - Ff
F = 360 N - 340 N
F = 20 N
F = m × a
20 N = 50 kg × a
a = 20 N / 50 kg
a = 0.4 m/s²
#LearnWithEXO
The acceleration of the box when the frictional force of 340 N is applied to the box will be 0.4 m/s².
What is acceleration?In mechanics, acceleration is the measure of how quickly the velocity of an object changes with respect to time. The magnitude of accelerations as a vector. The acceleration of an object depends on the direction of the net force acting on it.
It is a vector quantity because acceleration has both a magnitude and a direction. Additionally, velocity is a vector quantity. The change in the vector of velocity during a period of time divided by the period of time is the definition of acceleration.
According to the question,
F = F⁰ - [tex]F_f[/tex]
F = 360 N - 340 N
F = 20 N
Force = m × a
20 N = 50 × a
a = 20 N / 50 kg
a = 0.4 m/s²
So, the acceleration of the box will be 0.4 m/s².
