Answer: Yes and no.
Explanation: Mass is the amount of matter in an object, whereas weight is the force exerted on an object by gravity. Objects on the surface of the earth have weight, although sometimes the weight is difficult to measure.
Answer:
The police will cite you for speeding.
Explanation:
To know if the police will cite you for speeding we need to find the average speed (v):
<u>Where:</u>
x(f): is the final distance = 39 mi
x(i): is the initial distance = 0
t(f): is the final time = 53 min = 0.88 h
t(i): is the initial time = 17 min = 0.28 h
Hence, the average speed is:
Therefore, since the limit speed is 60 mph and your speed is 65 mph, the police will cite you for speeding.
I hope it helps you!
Answer:
F = 145 N
Explanation:
Given that,
Force applied by Jeff is 85 N and the force applied by Chris is 60 N. Both forces are acting in the same direction to push a rock up a hill. It means that net force is equal to the sum of these two forces.
So,
Net force on the rock = 85 N + 60 N
= 145 N
Hence, the net force on the rock is 145 N.

Answer:
Explanation:
Intensity, Io = 14.5 W/m²
θ = 25°
By the law of Malus
I = 11.91 W/m²
Now the formula for the rms value of magnetic field is given by
Brms = 2.23 x 10^-7 tesla
