Answer: states that energy can neither be created nor destroyed - only converted from one form of energy to another.
Explanation:
Answer:
The options are
A) isochoric.
B) isothermal.
C) adiabatic.
D) isobaric.
The answer is C. Adiabatic
Adiabatic process involves zero loss or gain of heat in a system. This is usually depicted as Q= 0.
An ideal gas being compressed in a well-insulated chamber using a well-insulated piston involves the use of adiabatic process. The insulated chamber and piston helps to prevent heat loss or gain of heat. This is because insulators are poor conductors of heat and electricity.
Answer:
v1=21.81m/s
Explanation:
<em>When a golfer tees off, the head of her golf club, which has a mass of 160 g, is traveling 50 m/s just before it strikes a 46 g golf ball at rest on a tee. Immediately after the collision, the club head continues to travel in the same direction but at a reduced speed of 44 m/s. Neglect the mass of the club handle and determine the speed (in m/s) of the golf ball just after impact.</em>
According to the law of conservation of momentum, if the net external force on a system is zero, then the linear momentum of the system is conserved.
During collision of two particles, the external force on the system of two colliding particles is zero (only internal force acts between the colliding particles), therefore, the momentum is conserved during the collision.
Answer and Explanation:
Given :
head of the golf club=160g
velocity of the golf club=50 m/s
golf ball mass=46g
velocity=om/s
m1u1+m2u2=m1v1+m2v2.........................................1
160*50 +46*0=160*44+46*v1
8000=7040+46v1
960=46v1
v1=960/46
v1=21.81m/s
Answer: B
Explanation:
The equation to find momentum is velocity*mass. Without velocity, there would be no momentum. Therefore the object CAN NOT be at rest.
The normal force exerted on the rover when it rests on the surface of the planet be greater is 3,125.22 N.
<h3>
What is normal force?</h3>
A normal force is defined as the force that a surface exerts on an object.
N = W
N = mg
where;
- m is mass of the object
- g is acceleration due to gravity
Normal force is proportional to the weight of an object be considered.
<h3>Normal force of the rover</h3>
N = mg
N = 1,063 kg x 0.3(9.8 m/s²)
N = 3,125.22 N
Thus, the normal force exerted on the rover when it rests on the surface of the planet be greater is 3,125.22 N.
