Newton would not agree with that explanation, and he would tell my brother to go to his room. Then Newton would turn to me and explain:

Once the soccer ball is in motion, it will continue moving in a straight line with constant speed, until external forces change its motion. (Newton's #1 Law of Motion).

There are external forces on the soccer ball after the kick: gravity, air resistance, and scraping through grass.

Gravity has no effect on its horizontal motion. But air resistance and scraping through grass are both friction ... they both rob kinetic energy from the ball. Once the kinetic energy of the ball is all gone, it doesn't move any more. An observer looking at the ball and measuring its motion would write in his notebook "The ball has stopped." .

Answer: $316.8V$

Explanation:

given data:

metre moving current = $0.96mA$

meters voltage = $288V$

or $0.96*300V = 288V$

Solution:

$v1 = (0.96mA*150)$

$= 144V$

$i1 = \frac{144v}{750}$

$= 0.192mA$

$i2 = imovement + i1$

$i2= 0.96mA+0.192mA$

$= 1.152mA$

$Vmeasured = 144V+(150)(1.152mA)$

$=316.8V$

the unknown voltage is 316.8V

What is the difference between speed and velocity?

ElenaW [278]

B - speed and direction are combined in another quantity, called velocity. It can be thought of as its speed in a particular direction. Speed is the corresponding scalar quantity, because it does not have a direction.

When an apple falls towards the earth,the earth moves up to meet the apple. Is this true?If yes, why is the earth's motion not n

Harlamova29_29 [7]

Answer:

because the mass of the apple is very less compared to the mass of earth. Due to less mass the apple cannot produce noticable acceleration in the earth but the earth which has more mass produces noticable acceleration in the apple. thus we can see apple falling on towards the earth but we cannot see earth moving towards the apple.
