Answer:
Refraction
Explanation:
Refraction, meaning passes through. Reflection is when light, heat, or sound bounces off a surface, kind of like an echo. Resonance is sound reverberating, or vibrating. And polarization is the action of not allowing the vibrations of a transverse wave. Hoped it help..
Answer:
U = 1000 J
Explanation:
By the conservation of energy, potential energy is converted into kinetic energy when the ball falls from a height.
U = Energy (in Joules)
m = mass (in kg)
v = velocity in (m/s)
g = acceleration due to gravity (in m/s^2)
h = height (in m)
Let's use as we have the values given.
Explanation:
a magnet should look something like this, so the south pole will be the side that is "receiving" the arrows from the north pole
Answer:

Explanation:
From the question we are told that:
Diameter
Distance
Generally the equation for circumference of a circle is mathematically given by
Therefore
Angular distance that the pie plate has moved through in revolutions is
Generally Angular distance that the pie plate has moved through in radians is
Generally Angular distance that the pie plate has moved through in degrees is
Answer:
Answer is option b) 2.97m
Explanation:
With the relationship between the force exerted by the runner and the mass that it has, I can determine the acceleration it will have:
F= m × a ⇒ a= (650 kg ×(m/s^2)) / (70kg)= 9.286 (m/s^2)
With the acceleration that prints the force exerted and the time I can determine the distance traveled in the interval:
Distance= (1/2) × a × t^2 = (1/2) × 9.286 (m/s^2) × ((0.8s)^2)= 2.97m
