An apple falls because of the gravitational attraction to earth. how does the gravitational attraction of earth to the apple com

pare? (does force change when you interchange m1 and m2 in the equation for gravity - m2 m1 instead of m1 m2 ?)

The forces between the apple and Earth are the same in magnitude. Force is the same either way, but the corresponding accelerations of each are different.

A student made the claim that a 4 gram paintball fired from a paintball gun at 90 m/s could have about the same kinetic energy a
vovikov84 [41]

This question involves the concept of kinetic energy.

The student's claim is "right".

<h3>Kinetic Energy</h3>

The energy possessed by a body, by the virtue of its motion is called kinetic energy. Mathematically it is given by the following formula:

K.E =\frac{1}{2}mv^2

where,

  • K.E = Kinetic energy
  • m = mass
  • v = velocity

Therefore,

For the paintball:

K.E = \frac{1}{2}(4\ g)(90\ m/s)^2

K.E = 16200 J

For the pellet:

K.E = \frac{1}{2}(1\ g)(180\ m/s)^2

K.E = 16200 J

Hence, both paintball and pellet will have same kinetic energy. The student is right.

1-Calculate Req
ArbitrLikvidat [17]

Answer:

1. 21.66 Ohms

2.  3.38 A

3. 6.7 V

Explanation:

1. Req = 6+2 = 8 Ohms (2 and 6 are in a series circuit)

  Req = 1/8 +1/4 = 3/8 = 8/3 = 2.66 Ohms (8 and 4 are parallel, so we will add them using this equation)

  Req = 2.66 + 1 + 9 + 3 + 6 = 21.66 Ohms

2. I = V/R = 9/2.66 = 3.38 A (In a series circuit, the current is the same across the resistors, so we will add them and divided them by 9 volts)

3. V = IR = 3.38 x 2 = 6.7 V (In a series circuit, the voltage is different, so each resistor will have a different voltage.)

I hope this helps.  I am not an expert in physics but its ok :)
