The acceleration that the net force will cause is 7.5 m/s²
To solve this problem, first, we need to find the net force.
⇒ Equation:
F = ma................ Equation 1
⇒ Where:
- m = mass of the box
- a = acceleration of the box
From the question,
⇒ Given;
⇒ Substitute these values into equation 1
We also use the same equation 1 to find the acceleration that the net force will cause to a box of mass 2.8 kg.
⇒ make a the subject in equation 1
- a = F/m................. Equation 2
⇒ Substitute the appropriate values into equation 2
Hence, The acceleration that the net force will cause is 7.5 m/s²

IF there is no air resistance, then he could drop a feather, a piece
of Kleenex, a school bus, and a battleship. If he dropped them all
at the same time from the same height, they would all hit the ground
at the same time.
Answer:
1.71
Explanation:
the parabolic movment is described by the following equation:
where y is the height of the ball, a is the angle of launch, 
the initial velocity, g the gravity and x is the horizontal distance of the ball.
So, if we want that the ball reach the hood, we will replace values on the equation as:
Finally, solving for , we get:
1.71
Kind of. A barometer measures air pressure. Not actual weather. Even though air pressure has a lot to do with the weather it is not exactly the same thing.
<u>Answer:</u>
A measurement standard is defined as 'the exact quantity people agree to use for comparison'.
<u>Explanation:</u>
For the same type of quantity, there is a unit of measurement which is defined and adopted either conventionally or by law which is used as standard for measurement of that quantity.
This measurement standard is defined as 'the exact quantity people agree to use for comparison'.
For example, for length the standard unit of measurement is 'meter'.
