Two particles, one with charge − 3.77 μC −3.77 μC and one with charge 4.39 μC, 4.39 μC, are 4.34 cm 4.34 cm apart. What is the m
Fudgin [204]

Answer:

the magnitude of the force that one particle exerts on the other is 79.08 N

Explanation:

given information:

q₁ = 3.77 μC = -3.77 x 10⁻⁶ C

q₂ = 4.39 μC = 4.39 x 10⁻⁶ C

r = 4.34 cm = 4.34 x 10⁻² m

What is the magnitude of the force that one particle exerts on the other?

lFl = kq₁q₂/r²

   = (9 x 10⁹) (3.77 x 10⁻⁶) (4.39 x 10⁻⁶)/(4.34 x 10⁻²)²

   = 79.08 N

Sensible heat involves a change in which aspect of a substance?
sergij07 [2.7K]

Sensible heat involves change in temperature of a substance. As the name suggests, it is the heat one can feel or sensed. When a system exchange sensible heat, its volume, pressure and state do not change. The sensible heat can be measured with the help of thermometer. The other type of heat is latent heat which involves change in state of the substance.

A 500 kg car is at rest at the top of a 72 m high hill. The car rolls to the bottom of the hill. At the bottom of the hill, the
rjkz [21]

Explanation: Solution

1.

Gravitational potential energy

U=mgh=500*9.8*50

U=245000 J

2.

Kinetic energy is present at bottom of the hill

K=(1/2)mV2=(1/2)*500*27.82

K=193210 J

3.

Work done by friction

W=193210-245000=-51790 J

Martin rides his motorcycle at 20 m/s. suddenly he sees a row of stones
Novay_Z [31]

Answer: Yes

Explanation:

Given

Martin initial speed is u=20\ m/s

Stones is at 170 m ahead

Deceleration a=2\ m/s^2

Using the equation of motion v^2-u^2=2as

Insert the values

0-20^2=2\times (-2)s\\s=\dfrac{400}{4}\\\\s=100\ m

So, it took 100 m to stop completely. Hence martin will be able to stop in time.
