Answer:
It will take the system 0.63sec to complete one full oscillation
Explanation:
The expression for period of a body in simple harmonic motion is
T=2*pi√m/k
Where T Is the period
m is the mass of the body
K is the spring constant
Given data
m = 7.5kg
e=15cm
k=750j/m2
Substituting our data into the expression
T=2*3.142 √ 7.5/750
T=6.284*0.1
T=0.63sec
Answer:
Newton's Second Law of Motion states that a force on an object is equal to the mass of the object multiplied by its acceleration (F=ma). ... When the punter kicks the ball, his foot exerts a force on the ball. The football then exerts an equal amount of force in the opposite direction on the kicker's foot.
<span>The question is asking us what is BEST to say about a runner who is running at a constant velocity? A constant velocity (=speed) means that they are not getting faster or slower - they are running exactly as fast all the time. This meanst that their speed does not change, so their change of speed is equal to 0. A change of speed is called acceleration so their C. Their acceleration is zero. - C is the correct answer. </span>
Answer:
FALSE
Explanation:
The answer is false.
The speed of the sound in water is faster when compared to the speed of sound in air. This is because, the particles in air is loosely packed and are far from each other as compared to water or liquid.
The water particles are close to each other than air particles, so water particles are able to transmit the vibrations of the sound faster than the air particles.
Therefore sound waves travels faster in water than in air.
Organs are made up of different types of organs.
