The answer then is false, if it has a trait that will help it survive in its environment then it will pass on the trait to its offspring. <span />

You test a moon buggy on Earth. When the buggy hits a bump, it oscillates up and down on its springs with a period of 4 seconds.

Blizzard [7]

Answer:

Remains same

Explanation:

$T$ = Time period of oscillation

$m$ = mass

$k$ = spring constant

Time period of oscillation is given as

$T = 2\pi \sqrt{\frac{m}{k} }$

we know that as we move from earth to moon, the value of spring constant "k" and mass "m" remains unchanged because they do not depend on the acceleration due to gravity.

Time period depends on spring constant inversely and directly on the mass.

hence the time period remains the same.

Two technicians are discussing an engine with an interference design. Technician A says if a valve remains open when its cylinde

maksim [4K]

Answer: Both Technician A and B are right.

Explanation:

Both Technicians are correct. when a valve remains open as it approaches the TDC(top dead center), they piston may strike the valve which would result to damage of the engine. Same applies when it is open as it approaches the top dead center as a valve train damage may occur. As the driven train is responsible for providing power to the wheels from the engine block.

Explain how a guitar produces sound by using the terms standing waves and resonance.

Rzqust [24]

<span>When an object is forced into resonance vibrations at one of its natural frequencies, it vibrates in a manner such that a standing wave is formed within the object. ... such patterns are only created within the medium at specific frequencies of vibration.</span>

A football player kicks a 0.94 kg football with a force of 2.4 N.

Artyom0805 [142]

2.6m/s²

Explanation:

Given parameters:

Mass of football = 0.94kg

Force on ball = 2.4N

Unknown:

The acceleration of the ball = ?

Solution:

According to Newton's second law of motion "the net force on a body is the product of its mass and acceleration".

Net force = mass x acceleration

Make acceleration the subject of the expression;

Acceleration = $\frac{net force}{mass}$

Acceleration = $\frac{2.4}{0.94}$ = 2.6m/s²
