Answer:
- increasing the distance between the objects
- decreasing the mass of one of the objects
- decreasing the mass of both objects
Explanation:
Got it right on Edge 2020.
The gravitational force is decreased by increasing the distance between the objects or decreasing mass of one or both of the objects
According to Newton's law of Universal Gravitation; The force of gravity is directly proportional to the product of the masses between two bodies and inversely proportional to the square of the distance between them.
F = Gm1m2/r^2
Where;
G = gravitational constantm1 and m2 are the masses of the objects r = distance separating the objects.F = gravitational forceWe can see from the formula above, that the following will result in the decrease of the force between two objects;

What is a uniform circular motion?It is defined as motion when the object is moving in a circle with a constant speed and its velocity is changing with every moment because of the change of direction but the speed of the object is constant in a uniform circular motion
Hence, runners sprinting across a straight track is a type of linear motion, the propeller of an aircraft in midair is performing the rotational motion, a car driving up a winding mountain road is a curvilinear motion, music being played on a stringed instrument, such as a guitar is a type of vibrational motion

Why is it important to describe motion in universal terms?
Answer:
Motion requires force to cause that change. The time you take to travel the distance depends upon speed; the distance travelled is measured as the length of a line between the start and end of a motion. It is an important aspect in physics. In our lives motion is important and impacts so many things that we do.
Explanation:
The motion of every object is relative, thus it is important to discuss this motion in universal terms which serves as a reference point.
The motion of an object occurs when there is change in the position of the object with time and the object moves in the direction of the applied force. This motion is influenced by the net force acting on the object.
For example:
The dimension of speed of object in motion is measured with two fundamental quantities (length and time);
speed = LT⁻¹
The motion of every object is relative, thus it is important to discuss this motion in universal terms which serves as a reference point.

You accidentally throw your car keys horizontally at 8.0 m/s from a cliff. If yours keys land 28 m from the base of the cliff, how high was the cliff? Question 10 options: 17.15 m 60 m 45 m 28 m
Answer:
[tex]45m[/tex]
Explanation:
Let [tex]V_0[/tex] be the horizontal speed of the keys and D be the horizontal distance covered by the keys.
[tex]V_0= 8.0 \frac ms[/tex]
[tex]D= 28 m[/tex]
The initial velocity in the vertical direction is [tex]0[/tex].
Let [tex]g[/tex] be the acceleration due to gravity, which always acts vertically downwards, so, it will not change the horizontal direction of the speed, i.e. [tex]V_0[/tex] will remain constant throughout the projectile motion.
Let [tex]t[/tex] be the total time of flight in seconds. So,
[tex]D= V_0t[/tex]
[tex]\Rightarrow 28=8t[/tex]
[tex]\Rightarrow t=3 s \; \cdots (i)[/tex]
Let [tex]H[/tex] be the hight of the cliff.
Now, from the equation of motion
[tex]s=ut+\frac 1 2 at^2\;\cdots(ii)[/tex]
Where is the displacement is the direction of force, is the initial velocity in the direction of force, is the constant acceleration due to force and is the time of flight.
Here, , and (negative sign is for taking the sigh convention positive in the direction as shown in the figure.)
From equation (ii)
[tex]-H=0\times t + \frac 1 2 (-g)t^2[/tex]
[tex]\Rightarrow H= \frac 1 2 gt^2[/tex]
Take [tex]g= 10 \frac m{s^2}[/tex] and put the value of [tex]t[/tex] from equation (i), we have
[tex]H=\frac 1 2 \times 10\times 3^2[/tex]
[tex]\Rightarrow H= 45 m[/tex].
Hence, the height of the cliff was [tex]45 m[/tex].

There are so many things that make human travel difficult.
Here are some ideas ;
1) Air and Water -Taking water and oxygen from the Earth is very expensive and very difficult. (Note that if there is lots of water, oxygen can be made from the water. Also, if there is carbon dioxide, oxygen can be made.)
2) Food - people will need to grow their own food on another planet - transportation to and from Earth is, again, too expensive. Plants need carbon dioxide and sunlight (real sunlight is best; artificial lighting will work, too.)
3) Energy - Human settlements will need to create their own energy. Energy can be created using the sun.
Note that these powers have their own advantages and disadvantages
4) Radiation - Radiation is harmful for people, plants and animals. On Earth, we are protected by a magnetic field and an atmosphere. Some planets and moons have neither; some have only one or the other. Very few have both. Some planets have very strong magnetic fields that create even more radiation. Crazy right .
5) Gravity - planets or moons with a lesser gravitational pull than the Earth will result in astronauts having smaller bone and muscle mass, which is a serious problem if they are to come back to Earth. The closer a planet's gravity is to Earth, the less of a problem this is.
6) Atmosphere - Some planets have no atmosphere while some have atmospheres that will crush people(Woah ) .It's easier to deal with low-pressure rather than high-pressure, but both are dangerous if there is an air leak.
7) Distance - the further a planet is from Earth, the harder it is to.
8) Temperature - The hotter or colder a planet is, the more energy it will take to change the temperature(and im not really sure how ).

Maria walks 20 ft north, 35 ft east, and 20 ft south to get to the pool. Find her distance and displacement.
Answer: distance = 75ft
displacement = 35ft east
The required displacement of maria to get to the pool is 35 ft and the distance is 75 ft.
What are distance and displacement?To solve this problem, we first need to understand the difference between distance and displacement.
Distance is the total length traveled by an object, regardless of its starting and ending points. In this case, the distance traveled by Maria would be the sum of the distances of each segment of her journey,
Distance = 20 ft + 35 ft + 20 ft = 75 ft
Displacement, on the other hand, is the straight-line distance from the starting point to the ending point, measured in a straight line.
So let's assume the movement of maria on coordinate where North and East are positive movements and West and south are negative now add the distances,
Displacement =20 + 35 - 20 = 35 ft
Thus, the required displacement of maria to get to the pool is 35 ft and the distance is 75 ft.

difference between weightlessness in space and weightlessness in earth
In space we feel weightlessness because the earth's gravity has less effect on us. The Earth's gravitational attraction at those altitudes is only about 11% less than it is at the Earth's surface. If you had a ladder that could reach as high as the shuttle's orbit, your weight would be 11% less at the top.

A rock is thrown straight upward with an initial velocity of 20 m/s where the downward acceleration due to gravity is -10 m/s^2. How long is the ball in the air before it returns to the thrower's hand?
Answer:
4 seconds
Explanation:
Given:
Δy = 0 m
v₀ = 20 m/s
a = -10 m/s²
Find: t
Δy = v₀ t + ½ at²
0 m = (20 m/s) t + ½ (-10 m/s²) t²
0 = 20t − 5t²
0 = 5t (4 − t)
t = 4

A person travels by car from one city to another with different constant speeds between pairs of cities. She drives for 40.0 min at 50.0 km/h, 8.0 min at 70.0 km/h, and 35.0 min at 35.0 km/h and spends 40.0 min eating lunch and buying gas. Determine the average sped for the trip. Determine the difference between the intial citties along the route.
Answer:
Average speed = 40.50 km/h (Approx)
Explanation:
Distance = Time × Speed
Total distance = (40/60) 50 + (8/60) 70 + (35/60) 35
Total distance = 33.33 km + 9.33 km + 20.17 km
Total distance = 62.80 km
Average speed = Total distance / Total time taken
Average speed = 62.80 / [(40+8+35+40)/60]
Average speed = 62.80 / 1.55
Average speed = 40.50 km/h (Approx)

a. 0.096 watts
b. 10.41 Watts
С. 10.41 Ampere
D. 1500 ampere
Answer:
С. 10.41 Ampere
Explanation:
Given that,
Power, P = 125 watts
Voltage, V = 12 volts
We need to find current. Power in terms of current and voltage is given by :
P = VI, I = current
[tex]I=\dfrac{P}{V}\\\\I=\dfrac{125\ W}{12\ V}\\\\I=10.41\ A[/tex]
So, the current is 10.41 A.
