An object with a mass of 5.4 kg has a force of 20.0 Newton’s applied to it. What is the resulting acceleration?
Answer:
Mass (m) = 5.4 kg
Force (f) = 20 N
Acceleration (a) = ?
Acceleration= m × a
[tex]m \times a \\ = 5.4 \times 20 \\ = 108 \: ms ^{ - 2} [/tex]
=> The resulting acceleration of the object is 108 m/s².

Haile's plane travels forward for a few feet and then begins to fall. What would explain the plane's ability to travel forward for a few feet without falling?
Answer:
Aircraft never crash because of one single issue. It's almost always a combination of factors that lead to an accident. Whilst flying is extremely safe, typical reasons why planes crash include pilot error, technical failures, bad weather, terrorism, and pilot fatigue.
Answer The force of the air pushing up on the plane is
equal to the force of gravity pulling down on the
plane.

Erosion and Weathering can cause changes in earths surface but how does erosion alone changes the earth surface.
Answer:
The action of erosion alone can change the earth's surface. Erosion can wash away nutrients on the earth's surface, change the appearance of the soil of a particular area over time, can bore holes, that form caves, change landscapes for example when the earth is hit with gully erosion by continuous water runoff over time. Erosion can move soil to a new area.
Explanation:
Weathering involves breaking down rock into smaller pieces without any form of formal movement of those broken rock pieces. These processes that can lead to weathering are caused by mechanical, chemical, and organic processes which can happen over time. Erosion can now move broken rock pieces or soil to another place by water or wind. Weathering and erosion constantly change the Earth's surface.

What effect would constriction of the blood vessels have on the body?
Answer:
When blood vessels constrict, the flow of blood is restricted or decreased, thus retaining body heat or increasing vascular resistance. this makes the skin turn paler because the blood reaches the surface, reducing the radiation of heat. hope this helps

What different forms of energy are present when an egg crashes into the egg catcher?
Answer:
An egg raised above the ground has potential energy due to the force of gravity. When dropped, the egg's potential energy is converted into the kinetic energy of motion. :)
Explanation:
After rubbing the hair on your head with a balloon, you determine there are 2.4 x 1018 electrons on your head. What is the charge, in coulombs (C), of your head?
Answer:
q = 0.384 C
Explanation:
The total charge present at the head can be easily found out by multiplying the charge on a single electron with the total number of electrons present on the head:
[tex]q = ne[/tex]
where,
q = total charge on head = ?
n = total no. of electrons on the head = 2.4 x 10¹⁸
e = charge on 1 electron = 1.6 x 10⁻¹⁹ C
Therefore,
[tex]q = (2.4\ x\ 10^{18})(1.6\ x\ 10^{-19}\ C)[/tex]
q = 0.384 C

Explain Newton's Law Of Gravity, and explain how the formula works correctly and combines mathematical arithmetic to figure out gravity.
Answer:
Explanation:
Newton's Law Of Gravity states two masses will have an attraction force that is proportional to their masses and inversely proportional to the square of their separating distance.
Mathematically it is expressed as Force = G * M1 * M2 / d^2 where
G is the gravitational constant, M1 and M2 are the masses and d is the separating distance.
Which beach balls have potential energy and not kinetic energy?
Answer:
Beach ball 4
Explanation:
it is because, Potential Energy = M G H
P(e) directly proportional to H.
if H increase then P energy also increases

Explanation:
A gas mixture has 10% O2, 50% Ar (40 gmw) and 40% Pu (244 gmw). What is the density of this mixture?
Answer: 5.39g/L
Explanation:
We need to calculate the average molar mass of the mixture which will be:
= (10 × 32) + (50 × 40) + (40 × 244) / 100
= (320 + 2000 + 9760) / 100
= 12080 / 100
= 120.8g/mol
Since the volume occupied is 22.4L and 1 mole of the gas will occupies 22.4L given the standard temperature conditions, then the density of the mixture will be:
= Mass / volume
= 120.8 / 22.4
= 5.39g/L
Therefore, the density of the mixture will be 5.39g/L.

The angular velocity is the ration of the change in the angle turned to time.
Why does the angular velocity increase?The angular velocity is the ration of the change in the angle turned to time. As such, the angular velocity is measured in radians per second. We have been told that the athlete is supposed to perform the jump between figures 1 and 2 in multiple somersaults.
Each time the athlete somersaults, the angular velocity changes. As such, the rate of change of the angular velocity between figures 1 and 2 would be quite high.
On the other hand, the athlete jumps straight vertically down between figures 2 and 3 and does not turn. Hence, the angular velocity decreases.
