Answer:
779.87 N/m²
Explanation:
Pressure = Force (F) / Area (A)
Recall :
Force = ma ; mass * acceleration due to gravity
a = 9.8 m/s² ; mass = 0.4kg
Force, F = 0.4 * 9.8 = 3.92 N
Area = πr² ; r = Radius = 4cm = 4 / 100 = 0.04 m
Area = π0.04² = 0.0050265 m²
Hence,
Pressure = 3.92 / 0.0050265
Pressure = 779.86670 N/m²
Pressure = 779.87 N/m²
The distance from the Earth to the Sun is 92.96 million mi.
Answer:Both will continue traveling at the same speed because there is no friction.
Explanation: Gravitational force or pull is the force acting to attract all object in and around the Earth to the center of the Earth. The Earth's Gravitational force acts as a Bar magnet.
When objects are working outside the impact of the force of Gravity,it will not matter whether the objects are of the same size or wether one is heavier than the other,in this case both objects will move at the same speed as there is no impact of the Force of Gravity.
Answer:
I do believe the answer is D. prism
Answer:
0.031 m
Explanation:
Density of copper = ρ = 8960 kg/m³
r = Radius = 0.262 m
m = Mass of plate = 61.5 kg
v = Volume of plate = Volume of cylinder = πr²h
So, thickness of plate is 0.031 m
