The answer is called alloys
Proton only. That’s the answer
Answer:
a) 10m
b)
i)
ii)
iii)
Explanation:
The first 2.0s the sprinter maintains a constant acceleration. So we have to use the Constant acceleration motion formulas to solve the first part of the movement, then we need to use the contant velocity motion formulas for the rest of the movement.
a)
b)
the sprinter run 10 meters with constant accelaration then it start a constant velocity movement, so:
i) x=50-10=40m
ii) x=100-10=90m
iii) x=200-10=190m
Answer: D. 40
Explanation:
Power = Force * Velocity
Force = 600N
Power needs to be converted to Watts:
= 24 * 1,000
= 24,000 W
24,000 = 600 * Velocity
Velocity = 24,000/600
= 40 m/s
Answer: D. Transmission
Explanation:
A body is considered opaque to radiation (generally thermal radiation) when its thermal transmittance (the amount of energy that passes through the body per unit of time) is null or zero.
In this sense, when an opaque body is placed in front of a light source, it is illuminated, there will be reflection and absorption of light, but not transmission.
