Explanation:
Given
Required
Determine the height
This question will be answered using the following equation of motion;
Take g as 9.8
This gives:
<em></em>
<em> (Approximated)</em>
<em></em>
<em>Hence; Height = 30.1m</em>
The third equation of free fall can be applied to determine the acceleration. So that Paola's acceleration during the flight is 39.80 m/
.
Acceleration is a quantity that has a direct relationship with velocity and also inversely proportional to the time taken. It is a vector quantity.
To determine Paola's acceleration, the third equation of free fall is appropriate.
i.e 
= 
± 2as
where: V is the final velocity, U is the initial velocity, a is the acceleration, and s is the distance covered.
From the given question, s = 20.1 cm (0.201 m), U = 4.0 m/s, V = 0.
So that since Poala flies against gravity, then we have:
= - 2as
0 = 
- 2(a x 0.201)
= 16 - 0.402a
0.402a = 16
a = 
= 39.801
a = 39.80 m/
Therefore Paola's acceleration is 39.80 m/.

Answer:
The push switch is closed and the door unlocks. ... The switch completes the circuit and a current flows through the coil. The coil becomes an electromagnet and its iron core becomes magnetised. The iron bolt is attracted to the electromagnet.

Answer:
mind the angle that the ball is at and subtract the answer from where the goal post is. You probably know that but my brain cant function what the answer is.
A. Outside on a summer day, there are less particles that the sound bounces off of (snow and wind absorb the sound)
B. Water, sound travels faster through denser objects. Water has a higher density than air.
C. High air pressure, sound moves faster through matter that is closer together. This can be said because sound can't travel through space. (There is no atmosphere and consistent particles in space for sound to go through)
D. A piece of steel, It's denser than wood and water.
E. 90% nitrogen and 10% helium, nitrogen is denser than helium so it will move faster
