Answer:

if a car is increasing it's acceleration uniformly in a unit time, the graph will be moving away from it's origin. that's how you get this kind of graph.

Which is a vector quantity
Korolek [52]

Explanation:

Physical quantities are usually designated as either vector or scalar quantities.

There are several fundamental quantities know out there that makes definition of the world possible. Derived quantities are obtained from these fundamental quantities.

  • A vector quantity expresses a quantity that shows both magnitude and direction.
  • With a vector, you know the amount or quantity of measurement taken and the directional attribute.
  • A scalar quantity is a quantity that shows magnitude but no direction.
  • For example velocity is a vector and speed is a scalar. If a body moves at 10m/s due east, that is a vector.

Two identical pebbles are dropped. The first is dropped from a height of 256 feet and the second is dropped from a height of 400
ehidna [41]

Answer:

4.022 seconds and 4.99 seconds

Explanation:

Hello!

The free fall of the stone corresponds to a uniformly varied rectilinear movement

d=V_0*t+1/2*g*t^2

Being a free fall the initial speed is zero.

The distance is positive when considered in the same direction and direction as acceleration and speed.

256 feet stone

79.25 m=0 m⁄s*t+1/2*9,8 m⁄s^2 *t^2

t = 4.022 seconds

400 feet stone

121.92m=0 m⁄s*t+1/2*9,8 m⁄s^2 *t^2

t= 4,99 seconds

Force of 10N down,10N to the right,and 5N to the left are acting on a ball .it acceleration horizontally to the right.what other
denpristay [2]

Answer:

A 10 N force pointing up

Explanation:

If the net acceleration of the object is horizontal pointing to the right, that means that all vertical forces must have canceled out, and the only ones "unbalanced" are the horizontal ones (10 N to the right minus 5 N to the left giving a net force of 5 N to the right).

Since they mentioned only one vertical force pointing down (10 N), there must be another one of same magnitude but pointing in opposite direction (up).

Then there must also be a 10 N force pointing up acting on the object.

the batter swings the bat and makes contact with the ball. when this occurs, the kinetic energy of the bat is transferred to the
Ghella [55]
It will possibly be A) chemical b/c it can make a sound like when the bar hits the ball it makes a sound correct?! and also it created heat especially when it hits the ball. and when the ball MOVES and the bar HITS it creates kinetic energy, but when you hit the ball it doesn’t create a new substance.
