state the factors that affect tha gravitational force
Explanation:
1. Mass of an object
2. Distance between the objects
Answer:
When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance. The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.

4. A sprinter begins from rest and accelerates at the rate of 2 m/s2 for 200 m.
a) What is the sprinter's velocity at the end of the 200 m?
b) How long does it take him to cover it?
c) What is his average velocity?
Answer:
v=28.28m/s t=14.14s average velocity =2m/s
Explanation:
Starting at rest the initial velocity is 0 substituting that in the first equation of motion v=u+atgives the final velocity but we first have to determine the time using the third equation of motion which is s=ut+1/2at^2 and then do the substitution. Average velocity is the determined by adding the initial and final velocity then divide it by 2
12. A measuring cylinder has 150ml. of water in it. When a stone is immersed into the measuring cylinder, the water level raised to 210cm. What is the volume of the stone?
Answer:
60ml
Explanation:
I'm going to assume you mean 210ml not centimeters. To find the volume all we do is subtract both values or with the formula [ f - i = v ] where f = final amount and i = initial amount.
210 - 150 = 60ml
Best of Luck!
The final level of water should be = 210
[tex] {cm}^{3} [/tex]
or 210 ml
━━━━━━━━━━━━━
Given:.Initial level of water = 150mlFinal level of water = 210 ml━━━━━━━━━━━━━
Need to find:Volume of stone =?━━━━━━━━━━━━━
Solution:The volume of stone will be equal to the change in level of water.
that's,
210 - 150 [tex] {cm}^{3} [/tex]
= 60[tex] {cm}^{3} [/tex]
Hence the volume of the stone is 60 [tex] {cm}^{3} [/tex]

● Provide details such as rotation and axis.
● For lunar and solar eclipse describe partial eclipse
and total eclipse. For seasons describe all four seasons.
● Identify the relative position of the sun and earth in each case.
● Use a cause and effect to show how the chosen phenomena
occurs.
A lunar eclipse occurs when the Moon moves into the Earth's shadow. This can occur only when the Sun, Earth, and Moon are exactly or very closely aligned (in syzygy) with Earth between the other two, and only on the night of a full moon.
help with the number 2 question
Answer:
It is frequently stated that the value of the acceleration due to gravity at the pole is larger than at the equator because the poles are closer to the center of the earth due to the earth's oblateness. ... The measured value is larger because the earth's density is not uniform but increases toward the center.
Answer:
as explained that poles have more gravitational
force (9.83m/s^2) as the poles of earth is nearer to the center because it is flat at poles
but certainly at equator is having less gravitational force (9.78m/s^2) as it is Farr from centre of earth because it is bulgded at equator.
hence, poles have more gravitational force as co.pared to that of equator.

a) A car accelerates uniformly at 3.7 m s⁻² as it passes a stationary road train. The initial speed of the car is 30 m s⁻¹, and it reaches the speed limit of 130 km h⁻¹ as it passes the front of the cab. Calculate the length of the road train. Give your answer to 3 significant figures. include units in your answer.
b) The braking distance of a road train travelling at 15 m s⁻¹ is 70 m. Assuming that the same deceleration is applied at all speeds, calculate the braking distance of a road train travelling at 25 m s⁻¹
(a) The length of the train is 54.6 m
(b) The braking distance of the road train is 194.44 m
The given parameters:
acceleration of the car, a = 3.7 m/s²
initial velocity of the car, u = 30 m/s
final velocity of the car, v = 130 km/h = 36.11 m/s
To find:
the length of the trainThe length of the train is the distance travelled by the car
The distance traveled by the car is calculated as:
[tex]v^2 = u^2 + 2as\\\\2as = v^2 - u^2\\\\s = \frac{ v^2 - u^2}{2a} \\\\where;\\\\s \ is \ the \ distance \ travelled \ by \ the \ car\\\\s = \frac{(36.11)^2 - (30)^2}{2\times 3.7} \\\\s = 54.585 \ m\\\\s \approx 54.6 \ m[/tex]
Thus, the length of the train is 54.6 m
(b) The braking distance of a road train travelling at 25 m s⁻¹
[tex]a = \frac{v_1^2}{2s_1} = \frac{v_2^2}{2s_2} \\\\Given;\\\\s_1 = 70 \ m\\\\v_1 = 15 \ m/s\\\\v_2 = 25 \ m/s\\\\s_2 = ?\\\\2s_2v_1^2 = 2s_1v_2^2\\\\s_2 = \frac{ 2s_1v_2^2}{2v_1^2} \\\\s_2 = \frac{s_1v_2^2}{v_1^2} \\\\s_2 = \frac{70\times 25^2}{15^2} \\\\s_2 = 194.44 \ m[/tex]
Thus, the braking distance of the road train is 194.44 m

A wombat runs south in a straight line with an average velocity of 5 m/s for 4
minutes and then with an average velocity of 4 m/s for 3 minutes in the same
direction.
What is the wombats total displacement?
What is the average velocity during that time?
We have that
The wombats total displacement is
[tex]d_t=2100m[/tex]
The average velocity during that time is
[tex]v_{avg}=5m/s[/tex]
From the question we are told that:
initial Velocity [tex]V_1=5m/s[/tex]
initial Time [tex]T_1=4min=>240sec[/tex]
Final Velocity [tex]V_2=4m/s[/tex]
Final time [tex]T_2=3min=>180sec[/tex]
a)
Generally, the equation for displacement is mathematically given by
d_t=(Initial +final) displacement
Where
initial displacement
[tex]d_1=V_1*t_1\\\\d_1=5*240[/tex]
[tex]d_1=1200m[/tex]
Final displacement
[tex]d_2=V_2*t_2\\\\d_2=5*180[/tex]
[tex]d_2=900m[/tex]
Therefore
[tex]d_t=(Initial +final) displacement[/tex]
[tex]d_t=1200+900[/tex]
[tex]d_t=2100m[/tex]
b)
Generally, the equation for Average velocity is mathematically given by
[tex]v_{avg}=\frac{d_t}{t_1+t_2}[/tex]
[tex]v_{avg}=\frac{2100m}{240+180}[/tex]
[tex]v_{avg}=5m/s[/tex]

The average speed of a soccer ball is 10.5 m/s.
What is speed?Speed is defined as the ratio of the distance moved by the object at a particular time. The unit of speed is measured in the meter per second, miles per hour, etc. The speed of an object is a scalar quantity and does not require any direction to represent it. It only requires magnitude to represent it.
Average velocity is defined as the sum of all the distances traveled by an object to the time taken by the object to cover the total distance.
Given that a soccer ball is kicked horizontally. its average speed if its displacement is 21.0 m after 2.00 seconds will be calculated as below:-
Speed = displacement / change in time
Speed = 21.0 m / 2.00 s
Speed = 10.5 m/s
Therefore, the average speed of a soccer ball is 10.5 m/s.

5. A ball with momentum of 16 kg x m/s strikes a ball at rest. What is the total momentum of both balls after the collision? a. -16kg x m/s b. -8 kg x m/s c. 8 kg x m/s d. 16 kg x m/s? help please
Answer:
D. 16 Kgm/s
Explanation:
Let the momentum of the two balls be A and B respectively.
Momentum A = 16 kgm/s
Momentum B = 0 kgm/s (since the ball is at rest).
Total momentum = A + B
Total momentum = 16 + 0
Total momentum = 16 Kgm/s
Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.
Mathematically, momentum is given by the formula;
Momentum = mass * velocity
If a diver displace water with a weight of 500N what is the upthrust on the diver?
Answer:
500 N
Explanation:
Natural bouyency will keep the diver in the same place, no matter what the mass of gfs. This means if the diver is displacing with a weight of 500 N, the upthrust will also be 500 N.
Upthrust on the diver will be 500 N
What is Upthrust?
It is the force exerted by a fluid on an object in upward direction .
Since , Upthrust = weight of the liquid displaced by a submerged part of the body
so, Upthrust = mg where m = mass of the body and
g = acceleration due to gravity
It is given weight of water displaced = 500 N
hence , Upthrust on the diver will be 500 N
