Answer:
answer is number (a) If the car is moving on a straight road....
Explanation:
The distance moved and magnitude of displacement are equal only in the case of motion along a straight line. Because displacement is the shortest path between initial and find path. So, for car moving on straight road, distance moved and magnitude of displacement are equal.

a marble rolls horizontally off a table that is 0.8m tall. if the marble lands 0.6m from the base of the table, what is the initial velocity of the marble?
The initial velocity of the marble from the given position is 1.49 m/s.
The given parameters;
height of the table, h = 0.8 mhorizontal distance traveled by the train, X = 0.6 mThe time of motion of the marble from the given height is calculated as;
[tex]h = v_yt + \frac{1}{2} gt^2\\\\h = 0 + \frac{1}{2} gt^2\\\\h = \frac{1}{2} gt^2\\\\t = \sqrt{\frac{2h}{g} } \\\\t = \sqrt{\frac{2\times 0.8}{9.8} }\\\\t = 0.404 \ s[/tex]
The initial horizontal velocity of the marble is calculated as follows;
[tex]X = v_0_xt\\\\v_0_x = \frac{X}{t} \\\\v_0_x = \frac{0.6}{0.404} \\\\v_0_x = 1.49 \ m/s[/tex]
Thus, the initial velocity of the marble from the given position is 1.49 m/s.

Which is likely TRUE of an individual whose body composition has little fat and is naturally lean?
OPTIONS:
A.
They have a high metabolism.
B.
They have a family history of obesity.
C.
They require less food than most people.
D.
Their body composition will never change.
Answer:
A
Explanation:
If an individual whose body composition has little fat and is naturally lean then they have a high metabolism, therefore the correct answer is option A.
What is exercise?The advantages of working out vary depending on the type of death a person experiences. Even if a person exercises, excessive sitting can cause a number of illnesses, many of which are fatal. The individual might also engage in mobile activities, in addition, to exercise to improve their fitness.
Any activity that involves bodily motions that increases a person's health, fitness, and well-being while reducing their chance of developing illnesses is considered exercise. It makes it possible for the person to maintain a healthy weight.
Therefore, if an individual whose body composition has little fat and is naturally lean then they have a high metabolism, therefore the correct answer is option A.

what is the average acceleration of a car that is initially at rest at a stop light and then accelerates to 24 m/s in 9.4 s?
Answer:
Below
Explanation:
To find the acceleration of the car you can use this formula :
vf = vi + at OR a = v/t
I'm going to use the first one because it explains the steps more clearly :
vf = 24 m/s
vi = 0 m/s
t = 9.4 s
a = ?
24m/s = 0 + (a)(9.4s)
24m/s = a9.4
Divide both sides by 9.4
a = 2.55319 m/s^2
Round to 3 sig figs
a = 2.6 m/s^2

A car drives 215 km west and then 85 km south. Find the distance and displacement of the car.
Answer:
Distance= 300 km
Displacement= 130
Explanation:
When you find distance you have to add
When you find displacemnet you subtract
If a car drives 215 kilometers west and then 85 kilometers south, then the distance and displacement of the car would be 300 kilometers and kilometers respectively.
What is displacement?Displacement is a vector quantity. This indicates that it has both a direction and a magnitude and that it is visually represented as an arrow that points from the starting position to the ending position.
As given in the problem, if a car drives 215 kilometers west and then 85 kilometers south, then we have to find the distance and displacement of the car,
The distance traveled by car = 215 kilometers + 85 kilometers
= 300 kilometers
The displacement covered by the car = √(215² + 85²)
= 231.2 Kilometers
Thus, the distance traveled by car would be 300 Kilometers and the displacement would be 231.2 Kilometers in the southwest direction.

What is the net force on charge placed at the center of square of length 1m? All charges have same magnitude of 2 micro coulomb.
Answer:
Electric Field intensity is zero.
The reason for that is:
All charges are placed at equal distances from the center of the square and have same magnitude and sign. This means they will exert equal and opposite forces on the test charge at the center. Net force will become Zero.

what force is needed to make a ball fall on earth if it had a mass of 13kg
I'd appreciate if someone could help me thank you
Newton's second law allows finding the answer for the force that attracts the body is 127.4N
Newton's second law indicates that the force that is the interaction between two bodies is directly proportional to the product of the mass and the acceleration.
F = m a
Where the bold letters indicate vectors, F is the force, m the mass, and the acceleration of the body.
When a body is close to the Earth there is an interaction between the body and the planet, we call this interaction weight, it is given by the relationship
W = m g
Where W is the force called weight, m the mass of the body and g the acceleration of the body, which in this case is called the gravity acceleration (g = 9.8 m / s²)
They indicate that the mass of the body is m = 13 kg, let's calculate the weight
W = 13 9.8
W = 127.4 N
In conclusion using Newton's second law we can find the answer for the force that attracts the body is 127.4N

Answer:
Yoour MOM
Explanation:
Two balls are dropped from rest and allowed to fall. If one ball is allowed to fall for 1 s and the other for 3 s compare the distances they have fallen.
The second ball traveled a greater distance when compared to the first ball because the second ball spent more time in motion.
The given parameters;
time of fall of the first ball, t = 1 stime of fall of the second ball, t = 3 sThe distance traveled by each ball is calculated using the second equation of motion as shown below.
The distance traveled by the first ball is calculated as follows;
[tex]h = u_0t + \frac{1}{2} gt^2\\\\h = 0 + \frac{1}{2} gt^2\\\\h = \frac{1}{2} gt^2\\\\h = (0.5\times 9.8\times 1^2)\\\\h = 4.9 \ m[/tex]
The distance traveled by the second ball is calculated as follows;
[tex]h = \frac{1}{2} gt^2\\\\h = (0.5\times 9.8\times 3^2)\\\\h = 44.1\ m[/tex]
Thus, the second ball traveled a greater distance because it spent more time in motion.
