Answer: The correct answer is "weight".

Explanation:

The expression for the weight is as follows;

w= mg

Here, m is the mass of the object, g is the acceleration due to gravity and w is the weight.

Weight: It is the force which is exerted by the gravity on an object. It varies place to place.

The weight of the object depends on mass and acceleration due to gravity.

The weight of the object on the moon is one sixth of the weight of the object on the earth whereas the mass of the object remains constant.

Density is defined as the mass per unit volume.

Therefore, the force that gravity exerts on an object is called weight.

Higher Current = ________ Moving Electric Charges (Electrons) *
Eva8 [605]

Answer:

Higher current is normally achieved by faster moving electrons.

Explanation:

  • Current is solely not the speed of the electric charges, but speed of the electrons is one of the factors that current depends on.
  • Current is the net charge flowing per unit time.
  • Current can be represented by:

            I=v×e×N×A

where,

                  I= current

                  e= electric charge

                  v= speed of electrons

                  N=no. of free electric charges per volume

  • The unit of current is Ampere, represented by A. It is flow of 1 coulomb of charge in 1 second.

The car has a constant deceleration of 4.20 m/s^2. If its initial velocity was 24.0 m/s, how long does it take to come to a stop
nalin [4]

Answer:

The time is 5.71 sec.

Explanation:

Given that,

Acceleration a= -4.20 m/s^2

Initial velocity = 24.0 m/s

We need to calculate the time

Using equation of motion

v = u+at[/tex]

Where, v = final velocity

u = inital velocity

t = time

a = acceleration

Put the value into the formula

0 =24.0 +(-4.20)\times t

t = \dfrac{-24.0}{-4.20}

t=5.71\ sec

Hence, The time is 5.71 sec.

A spaceship starting from a resting position accelerates at a constant rate of 9.8 meters per second per second. How long and ho
Verizon [17]

Accelerating at 9.8 m/s² means that every second, the speed is 9.8 m/s faster than it was a second earlier.  It's not important to the problem, but this number (9.8) happens to be the acceleration of gravity on Earth.

1% of the speed of light = (300,000,000 m/s) / 100 = 3,000,000 m/s .

Starting from zero speed, moving (9.8 m/s) faster every second,
how long does it take to reach  3,000,000 m/s ?

           (3,000,000 m/s) / (9.8 m/s²)  =  306,122 seconds .
                                                   (That's  5,102 minutes.)
                                                        (That's  85 hours.)
                                                     (That's  3.54 days.)

Speed at the beginning . . . zero .
Speed at the end . . . 3,000,000 m/s
Average speed . . . . . 1,500,000 m/s

Distance = (average speed) x (time)

               = (1,500,000 m/s) x (306,122 sec) = 4.592 x 10¹¹ meters

                                                                     =  459 million kilometers

                         That's like from Earth
                                                  to       Sun
                                                             to    Earth
                                                                    to        Sun.
