Answer:
i dont understand, can you put it in word form please.
Explanation:
Answer:
F = 852 N
Explanation:
We apply Newton's second law to the trailer :
F = m*a Formula (1)
F : net force exerted by the truck on the trailer Newtons (N)
m : mass of the trailer in kilograms (kg)
a : acceleration of the trailer in meters over second square (m/s²)
Data
a=1.20 m/s² : acceleration of the trailer
m=710 kg : mass of the trailer
We replace data in the Formula (1) to calculate the net force exerted by the truck on the trailer
F = (710 kg)*(1.20 m/s²)
F = 852 N
Answer:
V= 2.7 [v]
Explanation:
The value of the resistance is given by:
so:
We can calulate the voltage dropped using the Ohm's law:
Because when you spill water on it, the reflection comes from the surface of the water, not the ground glass.
3x10^8 m/s, or the ‘speed of light’ - this applies to the entire spectrum
