Four boys push on the front back and sides of a shopping cart. the boys in the front on the two sides push with a force of 60N.

the boy in back pushes with a force of 50N. which way does the cart move

Answer:

The cart will move backwards

Explanation:

To solve this problem we must make a free body diagram of the shopping cart and the forces acting on them. You have two boys pushing on the sides with a force of 60 [N] and the child on the front also pushes with a force of 60[N], the child behind pushes with a force of 50 [N].

 In the attached image we can see the free body diagram.

As shown in the attached image the shopping cart is displayed from above, the forces of children pushing on the sides, are canceled with each other as they are equal in magnitude and opposite in direction. While the force of the child pushing with 60 [N] is greater than the force of the child pushing with 50 [N] therefore the cart will move backwards, that is to the left as seen in the attached scheme.

The frequency heard by the moth is the frequency emitted by the bat by virtue of its speed; 38.0kHz. B) If the speed of the bat is increased, the frequency heard by the moth is higher.

<h3>What is the frequency heard by the moth?</h3>

It follows from the task content that the frequency of the emitted by the bat is heard by the moth and hence, the frequency heard by the moth is; 38kHz.

B) Since, the speed and frequency of sound waves are directly proportional, speed = wavelength × frequency; it therefore follows that when the speed of the bat is increased, the frequency heard by the moth is higher.

If 1.00 mol of an ideal monatomic gas initially at 77 K absorbs 100 J of thermal energy, what is the final temperature? Assume t
Ne4ueva [31]

Answer:

85 K

Explanation:

T₀ = initial temperature of the gas = 77 K

T = final temperature of the gas = ?

n = number of moles of monoatomic gas = 1.00 mol

R = universal gas constant = 8.314

c = heat capacity at constant volume = (1.5) R = (1.5) (8.314) = 12.5

Q = Amount of heat absorbed = 100 J

Amount of heat absorbed is given as

Q = n c (T - T₀)

100 = (1) (12.5) (T - 77)

T = 85 K

How quickly will a 4 kg ball be accelerated if it is struck by a 12 N force?
hodyreva [135]

Explanation:

Hey there!

Given that 4kg ball struck by 12 N force.

So, we need acceleration.

Force = Mass × Acceleration

And, so

Acceleration = Force / Mass.

Acceleration = 12/4

<u>Acceleration</u><u> </u><u>is</u><u> </u><u>equal</u><u> </u><u>to</u><u> </u><u>3m</u><u>/</u><u>s</u><u>²</u><u> </u><u>in</u><u> </u><u>SI</u><u> </u><u>units</u><u>.</u>

Hope it helps :)
