Answer:
1) A = 0.25 m², 2) V = 0.5 m³, 3) m = 1500 kg, 4) W = 14700 N,
5) P = 58800 Pa
Explanation:
1) The area of the base is square
A = L²
A = 0.5²
A = 0.25 m²
2) The block is a parallelepiped
V = A h
V = 0.25 2
V = 0.5 m³
3) Density is defined
rho = m / V
m = rho V
m = 3000 0.5
m = 1500 kg
4) The weight of a body is
W = mg
W = 1500 9.8
W = 14700 N
5) The pressure is
P = F / A
in this case the force is equal to the weight of the body
P = 14700 / 0.25
P = 58800 Pa
Answer:
30000 J = 30 kJ
Explanation:
Kinetic energy is the energy possessed by a moving object solely due to its motion.
You can get the K.E. of an object using the equation,
K.E. =
So you get,
K.E. =
= 30000 J = 30 kJ
Answer:
The answer is Low earth orbit
Answer:
a)
b)
c)
Explanation:
Given:
- mass of the object,
- height of the object above the spring,
- spring constant,
a)
When the object is dropped onto the spring whole of the gravitational potential energy of the mass is converted into the spring potential energy:
is the compression in the spring
b)
When there is a constant air resistance force of 0.6 newton then the apparent weight of the body in the medium will be:
Now the associated gravitational potential energy is converted into the spring potential energy:
c)
On moon, as per given details:
