Answer:
The force is Inertia
Explanation:
The force that acts on an object to move it from rest or a constant straight line motion is known as Inertia.
In physics the above statement is governed by Newton's first law of motion which is also known as Law of Inertia.
This law states that, an object that is at rest will remain at rest and an object that is moving will continue to move in a straight line with constant speed, if and only if the net force acting on the object is zero.
This implies that, A stationary object will remain motionless if no force acts on it while a object with constant velocity will continue moving with constant velocity until a force acts on it (neglecting resistance from air and friction).
technically usually the warmer object/substances particles move master which causes friction among the particles plus the kinetic energy being converted to thermal energy, so i would say the hand.
Answer:
ratio =0.3075 T
Explanation:
The magnetic field B creates a force on a moving charge such that
Now this causes a centripetal acceleration
so
...........(i)
...............(ii)
If accelerating potential V is same and then kinetic energy equals the potential energy difference
put these value in equation (ii)
simplifying we get
for same location r will be same in both case
..............(iii)
..........(iv)
dividing (iv) and (iii) equation we get
so on solving we get
=0.3075 T
Answer:
if no mistaken then it is 300kN
Explanation:
Using SI units (the default if a system is not specified) 200T = 200000kg as the mass of the whale, it would weigh 1960kN in 1g Earth gravity.
On the Moon, the acceleration is 0.166g, to it would weigh about 330kN.
The final answer is -322, 320 Joules. The solution for the problem is:
The equation that must be used in this problem is:
U = mCp(Tf-Ti)
where:
U = energy released or absorbed in Joules
m = mass in kg
Cp = specific heat of material in J/kg-C
Tf = final temperature, C
Ti = initial temperature, C
Looking up the Cp of granite gives a value of 790 J/kg-C.
U = 17kg (790 J/kg-C) (21-45)
<span>U = - 322, 320 Joules (negative means heat is released)</span>
