Answer:
G.P.E = 368.3
Explanation:
Given the following data;
Mass = 2.63kg
Height, h = 14.29m
We know that acceleration due to gravity is equal to 9.8m/s²
To find the gravitational potential energy;
Gravitational potential energy (GPE) is an energy possessed by an object or body due to its position above the earth.
Mathematically, gravitational potential energy is given by the formula;
Where;
G.P.E represents potential energy measured in Joules.
m represents the mass of an object.
g represents acceleration due to gravity measured in meters per seconds square.
h represents the height measured in meters.
G.P.E = 368.3
Note: the unit of gravitational potential energy is Joules.
Answer:
The force due to hammering changes the shape of the piece of iron
Explanation:
How hard you hammer the iron while it is hot will cause the iron to change shape or reform the way you want it.
Answer:
25000W
Explanation:
Kinetic Energy, EK=(1/2)mv2. Energy is conserved, so the work done by the brakes, W, must be equal to the change in kinetic energy of the car, ∆EK. Therefore: W = ∆EK = (1/2)1000(152-52) = 0.51000200 = 100000 = 1*105J. Since power P = W/T, the average power output of the brakes is equal to the total work done by the brakes over the time that the brakes are applied for, therefore: P = 100000/4 = 25000W.
Answer:
Planet Z will have the following properties;
Active Volcanoes
Active Tectonics
An Atmosphere produced by outgassing
Explanation:
The little terrestrial worlds have heat shorter than the much bigger terrestrial worlds, so the bigger worlds tend to have active volcanism and tectonics. These active volcanism and tectonics are likely to erase ancient craters. The active volcanism and tectonics would create an atmosphere by producing gases.
It is know that the Terrestrial worlds that are not far from the star have higher surface temperature.
Fast rate of rotation can cause winds and strong storms but here it is slower compared to earth. Also, a tilt of axis causes seasons.
The properties the star have are active volcanoes, active tectonics and an atmosphere produced by outgassing.
