I'd suggest double checking these if you can.
Explanation:
Each of these you can answer by plugging the numbers into the equation
[tex]F = G\frac{m_1 m_2}{r^2}[/tex]
G is the gravitational constant 6.673×10⁻¹¹ N m² / kg²
So the first one would be:
[tex]F = 6.673 \times 10^{-11} \frac{Nm^2}{kg^2} \times\frac{1kg\times 1kg}{(10m)^2}\\F = 6.673 \times 10^{-11} N \times\frac{1}{100}\\F = 6.673 \times 10^{-13}N[/tex]
I'm not going to run through showing all calculations for the rest, as you're in a rush, so to whip through them
2: 6.637e-09 N

5: 1.456e-06 N
6: 5.839e-07 N

A hurdler is 0.635 m from a hurdle when he jumps at 3.22 m/s at a 62.9 degrees angle. How many seconds later does he clear the hurdle? (Hint: it is not necessarily at the highest point in his motion.) (Unit = s) Watch sig figs.
Answers
Answer:
Explanation:
The horizontal distance of the hurdle = .635 m
This distance is covered by hurdler by horizontal component of his velocity
horizontal component of hurdler's initial velocity = 3.22 x cos 62.9
= 1.4668 m /s
displacement in horizontal direction = .635 m , acceleration = 0 as no force acts in horizontal direction .
So time taken to clear the hurdle
= .635 / 1.4668 s
= .433 s .

A car is traveling east at a speed of 25 m/s. It then takes
5 seconds to a stop at a red light (final velocity=0 m/s).
What is the acceleration of the car?
Answers
Answer:
-5m/s²
Explanation:
Given parameters:
Initial velocity = 25m/s
Time = 5s
Final velocity = 0m/s
Unknown:
Acceleration of the car = ?
Solution
The acceleration of a body is the rate of change of the velocity of the body with time.
Acceleration = [tex]\frac{Final velocity - Initial velocity }{time}[/tex]
So;
Acceleration = [tex]\frac{0 - 25}{5}[/tex] = -5m/s²
The car is decelerating at a rate of 5m/s²

Explanation:
Which statement is true? A. Inertia causes bodies to slow in their motion, unless they’re pushed by a force. B. Inertia resists changes to the state of motion of a body. C. Inertia decelerates a body. D. Inertia is due to friction.
Answers
Answer:
B. Inertia resists changes to the state of motion of a body.
Explanation:
From the given choices, it is true that inertia resists changes to the state of motion of a body.
Inertia is a form of force solely dependent on the weight of a body. This quantity defines the native ability of a body to resist changes in motion.
According to Newton's first law, the concept of inertia is even more clearly defined.
The law states that "an object will remain in a state of rest or of uniform motion unless it is acted upon by an external force" .

The model above shows sunlight that is directly hitting one side of the earth during its winter season. Which sentence explains why this area is experiencing shorter hours of daylight
Answers
Answer:
During winter time the northern hemisphere leans away from the sun due to the rotation of earth and due to this change the sunlight is not direct on these areas instead it is spread and due to this the shadows are longer and the sunlight is not intense. The earths rotation around the sun causes the seasons to change and that is why we experience shorter hours of daytime.

What can increase the gravitational potential energy of a object
Answers
Answer:
Increase in mass and height
Explanation:
The gravitational potential energy of an object can increase if the mass and height of object is increased.
Gravitational potential energy is the energy due to the position of a body.
It is expressed as:
Gravitational potential energy = mass x acceleration due gravity x height
Increasing mass and height will cause an increase in gravitational potential energy.
How does convection create wind patterns at a beach? A. The Sun heats the water and the land equally during the day, but at night heat from the land rises, causing warm air over the water to rush toward shore. B. Electromagnetic waves from the Sun are absorbed in Earth's atmosphere, which is warmed and then reemits the heat as electromagnetic waves. C. Increasing temperature means greater kinetic energy, and the kinetic energy shows itself as movement of the air molecules. D. During the day, air over the warm land heats up and rises, while cooler air that was over the water is drawn in to shore to replace it. SUBMIT
Answers
Answer:
D. During the day, air over the warm land heats up and rises, while cooler air that was over the water is drawn in to shore to replace it.
Explanation:
Convection creates wind patterns at a beach by the force of land and sea breeze which are different wind patterns that move air masses.
Convection is a form of heat transfer that occur mainly in fluids such as gases and in liquids.
During the day, the air over the land is warmed. The land is a good conductor heat better than the ocean. This air masses rises and move towards the ocean. The colder air from the ocean moves landward to replace this air mass.
As the cold air gets warmer at land, it rises and move ocean-ward again.

Compared to yesterday, you did three times the work in one-third the time. To do so, your power output must have been
a. the same as yesterdays power output
b. one-third yesterdays power output
c. three times yesterdays power output
d. nine times yesterdays power output
Answers
Answer:
D. nine times yesterdays power output
Explanation:
We know that formula for power with work is;
Power = workdone/time taken
Now, you did three times the work in one-third the time yesterday.
This means that;
Work yesterday; W_yesterday = W
Work today; W_today = 3W
Time yesterday; T_yesterday = t
Time today; T_today = t/3
Thus,power today is;
P_today = 3W/(t/3)
P_today = 9(W/t)
Since power output yesterday is W/t, it means you did nine times yesterday's power output.
Answer:
D
Explanation:
Nine times yesterday's power output.

What is potential energy ?"Potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors." An object can store energy as the result of its position. For example, the heavy ball of a demolition machine is storing energy when it is held at an elevated position. This stored energy of position is referred to as potential energy. Similarly, a drawn bow is able to store energy as the result of its position.

A negative charge of - 0.0005 C exerts an attractive force of 9.0 N on a second charge that is 10 m away. What is the magnitude of the second charge?
Answers
Answer:
q₂ = 0.0002 C
Explanation:
Given that,
Charge, q₁ = -0.0005 C
The force between two charges, F = 9 N
The distance between charges, d = 10 m
We need to find the magnitude of the second charge. The force acting between two charges is given by :
[tex]F=\dfrac{kq_1q_2}{r^2}\\\\q_2=\dfrac{Fr^2}{kq_1}\\\\q_2=\dfrac{9\times (10)^2}{9\times 10^9\times 0.0005}\\\\q_2=0.0002\ C[/tex]
So, the magnitude of the second charge is 0.0002 C.
