Answer: The correct answer is "The wave will bend or defract".

Explanation:

Diffraction: It is the phenomenon in which the light gets bend around the corner of the aperture or a slit. There is a spreading of the waves as they pass through an aperture.

The wavelength of the wave is comparable or greater than the size of the aperture to observe diffraction. If the wavelength of the wave is not comparable or greater than the size of the aperture then in this case, the diffraction is unnoticeable.

In the given problem, a wave is approaching a barrier that has a small hole at the center. A small hole is aperture here. The wave will bend or defract. The diffraction phenomenon will occur in this case.

Therefore, the correct option is (B).

notka56 [123]

Answer:

Newton's first law

Explanation:

Newton's first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force. Therefore, when the ice is smooth, friction gets lesser, and the force acted on that Puck will be decreased.

A school bus has a mass of 18,200 kg. The bus moves at 13.5 m/s. How fast must a 0.142-kg baseball move in order to have the sam
nikitadnepr [17]

Answer:

bus momentum

p_bus= m_bus x v_bus

=18,200 x 16.5

basball momentum

pball=mball x vball

=0.142 x v

p_bus = pball

18200 x 16.5 = 0.142 x v

v=(18200 x 16.5)/0.142

v is the answer for baseball

To obtain the same resistance force, a greater force must be exerted in a machine of lower efficiency than in a machine
Sindrei [870]

Answer: True.

Explanation:

A resistance force is also known as friction. And the efficiency of a machine is affected by friction.

A machine of lower efficiency has higher magnitude of friction than a machine of higher efficiency.

Therefore, To obtain the same resistance force, a greater force must be exerted in a machine of lower efficiency than in a machine of higher efficiency. This is true
