The force between to objects of charge +Q and -2 Q, respectively, is measured as -2F. If the charge on the first object is doubled and the distance between the objects is doubled
<u>b.-2f </u>
Answer:
The amount of heat flow is . How does heat flow through solids? Conduction is the transfer of heat through solids. Factors that affect rate of heat flow include the conductivity of the material, temperature difference across the material, thickness of the material, and area of the material.
Explanation:
Answer:
<em>13 m/s²</em>
Explanation:
Mass of object = 200 Kg
Applied force = 2600 N
Acceleration = ?
Solution:
Definition:
The acceleration is rate of change of velocity of an object with respect to time.
Formula:
a = Δv/Δt
a = acceleration
Δv = change in velocity
Δt = change in time
Units:
The unit of acceleration is m.s⁻².
Acceleration can also be determine through following formula,
F = m × a
a = F/m (N = kgm/s²)
a = 2600 kgm/s² / 200 Kg
a = 13 m/s²
Since the two trains are passing in opposite
directions, so this means that their relative velocities will be the sum of the
two trains that is:
<span>
relative velocity = (13 + 28) = 41m/s</span>
<span>
a. The passengers aboard on train B will see that train A is
moving at 41m/sec due east</span>
<span>b. The passengers aboard on train A will see that
train B is moving at 41m/sec due west</span>
The answer is 1.5....
The refractive index n = (Speed of light, c) /( Speed of light, v)
So c= n x v
comparing to c= 1.5 x v in this situation we see that n= 1.5
