The derivative of the function space as a function of time is equal to a function of speed as a function of time.
The velocity vector is given by the vector sum of the velocities of both axes.
If you notice any mistake in my english, please let me know, because I am not native.
Because the object is still made of the same material
Density is not affected by the weight and shape of an object its affected by how concentrated the atoms are in a given volume
Answer:
C. 21 Joules
Explanation:
We apply the formula to calculate the potential energy (Ep):
Ep=m*g*h
Where:
Ep : potential energy in Joules (J)
m :mass in kilograms (kg)
g acceleration due to gravity (m/s²)
h: height in meters (m)
Calculation of the height (h)
Ep = m*g*h
7 = (1.5 )*(9.8) *(h
)
7 = (14.7) (h
)
h = 7 / (14.7)
h= 0.476 m
Gravitational potential energy of the second object
Ep = m*g*h
Ep = (4.5 )*(9.8) *(0.476
)
Ep = (4.5 )*(9.8) *(0.476
)
Ep = 21 J
500J
Explanation:
Given parameters:
Weight of the body = 50N
Height = 10m
Unknown:
Work done = ?
Solution;
Work done is the force that moves a body through a particular distance in the direction of the force.
In this problem, we can solve the problem by relating work done to the potential energy used in lifting the mass.
The weight on a body, a force in the presence of gravity
weight(weight) = mg
where m = mass of body
g = acceleration due to gravity
Work done = Fxd
Where F = force on the body
d = distance moved
Potential energy = mgh
where h is the height
P.E = work done = Weight x height = 50 x 10 = 500J

Answer: Scattering reflection
Sunlight reaches earth's atmosphere and is scattered in all directions by all the gasses and particles in the air. Blue light is seen more than others because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.
