Answer:

Amy's average speed is equal to Chris's average speed.

Explanation:

Average speed is the ratio of total distance and total time interval

So here for Amy we know that

total distance = 3 + 2 + 1 + 4

d_1 = 10 units

now the average speed of Amy is given as

v = \frac{d}{t}

v = \frac{10}{2}

v = 5 units/hour

Similarly for Chris we will have

distance = 10 + 3 + 2

time = 3 hour

average speed = \frac{15}{3}

v = 5 units/hour

so correct answer is

Amy's average speed is equal to Chris's average speed.

An object, initially at rest moves 250m in 17s. What is it's acceleration?
Gekata [30.6K]
With the values you've given, only velocity can be found.
Acceleration is rate of change of velocity

d= 250s
t= 17s

a= d/t
 =\frac{250}{17}
 = 4.7 \frac{m}{s}

Complete the sentences below correctly. Stunt Car A and Stunt Car B are identical cars with the same mass of 48.9 kg. They are b
ivann1987 [24]

Answer:

Stunt Car A experiences a large force over a short period of time. Stunt Car B experiences a small force over a long period of time. Because of the force experienced by Stunt Car A, it will sustain more damage than Stunt Car B.

Explanation:

Both cars have the same mass and velocity, therefore they have the same momentum. During the collision, the total momentum of the car A and brick wall is conserved as well as the total momentum of the car B and the pile of leaves.

However, if we are to investigate the damage on each car, we should look at the cars not the whole system. So, the momentum difference between the cars gives us the impulse that the car felt.

\vec{J} = \Delta \vec{P}\\\vec{F}\Delta t = \vec{P}_2 - \vec{P}_1

Since the Car A will crash the wall quicker than the other car crashes through the pile of leaves,

\Delta t_1 < \Delta t_2

which gives us

F_1 > F_2

Assume that before separation, the weight of the milk bottle's contents (mixed milk and cream) is wmix. How does the combined we
finlep [7]

Answer:

Wsep = Wmix

Explanation:

When Cream and milk up in a bottle they might appear homogeneous but after the bottle must have settled down for a while i.e kept in a position without shaking the bottle. the contents ( cream and milk ) will be separated. this is because Milk and cream do not mix up just like some other liquids that don't mix-up. Wmix represents the weight of the bottle before separation while Wsep represents the weight after separation. but since both liquids are in the same bottle the weight after separation would remain the same

Wsep = Wmix

the electric field midway between two equal but opposite point charges is 573 n/c , and the distance between the charges is 16.0
saveliy_v [14]

The electric potential  between the two charges is 91.68 V.

<h3>Electric potential between the two charges</h3>

The electric potential  between the two charges is calculated as follows;

V = Ed

where;

  • V is electric potential
  • E is electric field
  • d is the distance of the charge

Substitute the given parameters and solve for electric potential,

V = 573 N/c x 0.16 m

V = 91.68 V

Thus, the electric potential  between the two charges is 91.68 V.
