When an object moves, stops moving, changes speed, or changes direction, how do scientists describe that condition? Question 1 o
Dominik [7]

If an object moves, stops, changes speed, or even changes direction, then that condition represents the unbalanced force condition.

Unbalanced Force:

The unbalanced force is the magnitude of the net force that tends to cause the motion of objects. It is nothing but the greater amount of force to be applied to the object to displace the object in either direction.

If an object is moving, stopping, changing the speed, or changing the direction, then such activities directly show that the object is changing its state of motion. And the change in the motion is only caused when there is some magnitude of force associated with it.

  • When the magnitude of forces applied on an object such that one force is greater than another in a specific direction, then such forces are known as unbalanced forces.
  • Unbalanced forces cause motion, which means a body can move, stop or even can change its direction due to the unbalanced force.

Thus, we can conclude that if an object moves, stops, changes speed, or even changes direction, then that condition represents the unbalanced force condition.

Two solenoids are equal in length and radius, and the cores of both are identical cylinders of iron. However, solenoid A has fou
Ira Lisetskai [31]

Answer:

\dfrac{L_A}{L_B}=16

Explanation:

\mu_0 = Vacuum permeability = 4\pi \times 10^{-7}\ H/m

n = Number of turns

A = Area

I = Current

Self inductance is given by

L=\mu_0n^2IA

Here, A has more turns so the self-inductance of A will be higher

For A

L_A=\mu_0n_A^2IA=\mu_0(4n_B)^2IA     [\because n_A=4n_B]

For B

L_B=\mu_0n_B^2IA

Dividing the above two equations we have

\dfrac{L_A}{L_B}=\dfrac{\mu_0(4n_B)^2IA}{\mu_0n_B^2IA}\\\Rightarrow \dfrac{L_A}{L_B}=16

\therefore \dfrac{L_A}{L_B}=16

tino4ka555 [31]

Answer:

1595790 gallons

Explanation:

Given that;

3.8 L = 1 US gallon

303,200.0 liters = 303,200.0 * 1/ 3.8 = 79789.5 gallons

If a wave is made every 90 seconds which is 1.5 mins

Then;

Number of waves made in 30 minutes = 30/1.5 = 20 waves

if each uses 79789.5 gallons, then 20 waves will use 20 * 79789.5 gallons = 1595790 gallons

The motion of a car on a position time graph is represented with a horizontal tine What does this indicate about the car's motio
GalinKa [24]

Answer:

Position-Time graphs display the motion of a object by showing the changes of velocity with respect to time.

The motion of a car on a position-time graph that is represented with a horizontal line indicates that the car has stopped moving.

A straight line with a positive slope indicates that the car is moving at a constant velocity, and thus the slope is constant. On the other hand, a curve with a changing slope, shows that the velocity is changing.
