Explain why there is no acceleration horizontally on an object in Projectile Motion. A. There is no acceleration horizontally be

cause velocity is constant in the x- direction. B. There is no acceleration horizontally because velocity increases in the x- direction. C. There is no acceleration horizontally because velocity decreases in the x-direction . D. There is no acceleration vertically because velocity is constant in the y -direction .

Answer:

Option  A is correct.

Explanation:

The force of gravity does not affect the horizontal component in projectile motion; a projectile maintains a constant horizontal velocity. So there is no acceleration ( a=0 ) in horizontal direction as velocity remains constant.

Car X traveled 3d distance in t time.  Car Y traveled 2d distance in t time. Therefore, the speed of car X, is 3d/t,  the speed of car Y, is 2d/t. Since speed is the distance taken in a given time.

In figure-2, they are at the same place, we are asked to find car Y's position when car X is at line-A. We can calculate the time car X needs to travel to there. Let's say that car X reaches line-A in t' time.

V_x .t' = 3d\\ \frac{3d}{t} .t' = 3d\\ t'=t

Okay, it takes t time for car X to reach line-A. Let's see how far does car Y goes.

V_y.t = \frac{2d}{t} .t = 2d

We found that car Y travels 2d distance. So, when car X reaches line-A, car Y is just a d distance behind car X.

That's the cool thing about free fall.  The amount of time it takes to fall remains the same.

In this case, a ball that is simply dropped from rest will fall at the same rate as a ball that had some umph in the horizontal direction.

Which part of the electronic system of a tape player would be different from that of a record player?
Luda [366]

Answer:

In a tape player sound is stored in the tape then from the tape,sound is converted to electrical signals then to the ears where as in a record player electric signals from the spinning cord are feed directly into an amplifier connected to a loudspeaker for us to hear.

Explanation:

In a record player, magnetic devices convert sound vibrations originating from from a spinning record into electric signals that are feed into an amplifier in a loudspeaker to make us hear the sound.A tape player utilizes a magnetic tape as the medium where the sound is stored into the tape.Here sound waves are converted into electric signals in the recorded and the sound wave goes to our ears due to polarity changes caused by the small magnets in the headphones.

What is the volume in liters of the basketball?
babymother [125]

he basket ball diameter used by NBA men players is around 9.55 inches

So diameter = 9.55 inch = 0.243 m

So radius of basket ball = 0.1215 m

Volume , V=\frac{4}{3} \pi r^3

V = \frac{4}{3}* \pi *0.1215^3=0.0075 m^3=7.5 L

So volume of basket ball used by men NBA players = 7.5 L
