Answer:
(a). The distance is 49.79 m.
(b). The speed of the ball is 24.39 m/s.
Explanation:
Given that,
Speed = 20 m/s
Angle = 40°
Height = 22 m
Time = 3.25 sec
(a). We need to calculate the distance
Using formula of distance
Put the value into the formula
(b). We need to calculate the horizontal velocity
Using formula of velocity
Put the value into the formula
We need to calculate the vertical velocity
Using equation of motion
Put the value into the formula
Negative sign shows the opposite direction.
We need to calculate the speed of ball
Using formula of speed
Hence, (a). The distance is 49.79 m.
(b). The speed of the ball is 24.39 m/s.
Answer:
A. The volume of the object
Explanation:
First of all, it can only PROBABLY be A or D
But why is it only A?
- Mass = The amount of matter in an object (nothing related here)
- Volume = How much space is the object taking (super related here)
It's VOLUME here and not MASS here because:
- It it would be Mass, then the object size could be anything, but the liquid wouldn't move as much higher.
- But because it is Volume, it is taking space, which makes the liquid move
- If the Mass would be the answer, then it would be totally not related, because mass isn't related over here, it matters about size.
<h2>
Hence, A. The volume of the object </h2>
is your answer!!!!
Answer:
absorption and insolation.
Explanation:
A force sets an object in motion when the force is multiplied by the time of its application.
