KE = ½mv²
<span>1.1 x 10^9 = ½ x 8 x 10^4 v²
v² = 2.75 x 10^4
v ≈ 165.8 m/s</span>
Answer:
A rise in temperature increases the kinetic energy and speed of particles; it does not weaken the forces between them. The particles in solids vibrate about fixed positions; even at very low temperatures. Individual particles in liquids and gases have no fixed positions and move chaotically.
Explanation:
Answer:
0.1
Explanation:
mass, m = 5 kg
θ = 60°
Force, F = 10 N
velocity is constant , it means the net force is zero.
So, the component of force along the surface is equal to the friction force
FCosθ = friction force
10 x cos 60 = μ x m x g
where, μ is the coefficient of friction
5 = μ x 5 x 9.8
μ = 0.1
Thus, the coefficient of friction is 0.1
I would say the energy transformation that happens would be potential energy to kinetic energy. Potential energy is the energy possessed by an object when at rest. As you eat a meal, you store potential energy. As you move around, this energy is used and is transformed to the energy of motion which is the kinetic energy.
Explanation:
Given that,
Mr. Hershman has purchased a farm that is in the shape of a rectangle. The dimensions of the piece of land are 4.3 km by 4.85 km. The area of the rectangle is given by :
So, she must buy 
of area.
Since, 
So, the area of rectangle is 2085.5 hectares. Hence, this is the required solution.
