1. What is the gravitational force of attraction between two 800 kg spherical objects that are 5 m apart? What would the gravitational force of attraction between these two objects be if the distance between them was changed to 10 m?
Answer:
the force of gravity between them is quadrupled .
Explanation:
Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces.
Can some one help me please and thanks
Answer:
The way in which objects exert forces on each other is described by Newton’s 3rd law of motion
Explanation:
Objects with mass exert forces on each other via the force of gravity. This force is proportional to the mass of the two interacting objects and is inversely proportional to the square of the distance between them. The factors G, M, and rare the same for all masses at the surface of the Earth.

How should the student change the circuit to give negative values for current and
potential difference?
Answer:
changing the polarity or direction of the battery changes the sign of the voltage and the current
Explanation:
The sign of current and voltage are due to established conventions.
The way that a DC circuit with negative current values is by changing the polarity of the power source or by inverting the battery, this creates that the electrons move in the opposite direction
Changing the battery also changes the direction of the power difference, since the potential from positive to negative, in most cases negative is assigned a potential of zero volts
In summary, changing the polarity or direction of the battery changes the sign of the voltage and the current

where is the centripetal force directed on a banked curve?
Answer:
The net force on a car traveling around a curve is the centripetal force, Fc = m v2 / r, directed toward the center of the curve.
Explanation:LET ME KNOW IF ITS WRONG. HAVE A NICE DAY!!!!!!!!!!
Answer: The net force on a car traveling around a curve is the centripetal force, Fc = m v2 / r, directed toward the center of the curve. The centripetal force is directed at right angles to the motion and also along the radius towards the centre of the circular path. In order for a car to move around a circular track, something must provide a centipetal force. One source of the centripetal force is friction between the tires and the road. This means that the tires do not need to supply any friction at all to keep the car from slipping sideways. ...

A machine has mechanical advantage 2,what does it mean?
Answer:
The mechanical advantage of a machine is 2. Mechanical advantage MA is the ratio of output (generated by the machine) force to input (applied to the machine) force. So MA = 2 means that for example if you apply 100 N then your machine will multiply that force and generate 200 N .
A paintball is fired horizontally from a tower 45 m above the ground. If the paintball gun fires at 90 m/s… How long does it take for the paintball to hit the ground? How far away from the tower will the paintball land?
Answer:
The time taken for the paint ball to hit the ground is [tex]t = 2.143 \ s[/tex]
The distance of the landing point from the tower is [tex]d = 192.86 \ m[/tex]
Explanation:
From the question we are told that
The height of the tower is [tex]h = 45 \ m[/tex]
The speed of the paintball in the horizontal direction is [tex]v_x = 90 \ m/s[/tex]
Generally from kinematic equation we have that
[tex]h = ut + \frac{1}{2} at^2[/tex]
Here u is the initial velocity of the paintball in the vertical direction and the value is 0 m/s , this because the ball was fired horizontally
a is equivalent to [tex]g = 9.8\ m/s^2[/tex]
t is the time taken for the paintball to hit the ground
So
[tex]45 = 0* t + \frac{1}{2} 9.8 * t^2[/tex]
=> [tex]t = 2.143 \ s[/tex]
Generally the distance of its landing position from the tower is
[tex]d = v * t[/tex]
=> [tex]d = 90 * 2.143[/tex]
=> [tex]d = 192.86 \ m[/tex]

The car's initial speed was 15 m / s and the distance the car travels before it comes to a complete stop after the driver applies the brakes is 63m. What is the magnitude of the car's acceleration?
Initial speed of the car (u) = 15 m/s
Final speed of the car (v) = 0 m/s (Car comes to a complete stop after driver applies the brake)
Distance travelled by the car before it comes to halt (s) = 63 m
By using equation of motion, we get:
[tex] \bf \longrightarrow {v}^{2} = {u}^{2} + 2as \\ \\ \rm \longrightarrow {0}^{2} = {15}^{2} + 2 \times a \times 63 \\ \\ \rm \longrightarrow 0 = 225 + 126a \\ \\ \rm \longrightarrow 126a = - 225 \\ \\ \rm \longrightarrow a = - \dfrac{225}{126} \\ \\ \rm \longrightarrow a = - 1.78 \: m {s}^{ - 2} [/tex]
[tex] \therefore [/tex] Acceleration of the car (a) = -1.78 m/s²
Magnitude of the car's acceleration (|a|) = 1.78 m/s²

A ball is thrown up into the air with the initial velocity of 18 m/s. A) How high does the ball go? B) Calculate the time needed for the ball to reach its max height.
Answer:
(a) h = 16.53 m (b) t = 1.83 s
Explanation:
Given that,
The initial velocity of a ball, u = 18 m/s
When it reaches to the maximum height, its final velocity v will be 0. Let it goes to a maximum height of h meters.
Finding t using first equation of motion as follows :
v = u +at
Here, a = -g and v = 0
[tex]t=\dfrac{u}{g}\\\\t=\dfrac{18}{9.8}\\\\t=1.83\ s[/tex]
The time needed for the ball to reach its max height is 1.83 s.
Let h is the maximum height. Using second equation of motion to find it :
[tex]h=ut-\dfrac{1}{2}gt^2\\\\h=18(1.83)-\dfrac{1}{2}\times 9.8\times (1.83)^2\\\\h=16.53\ m[/tex]
So, it will go to a maximum height of 16.53 m.

A truck moving due south takes a turn and starts moving towards east while maintaining the same speed.
Its velocity remains constant.
It covers unequal distances in equal intervals of time.
Its velocity changes
None of the above
Answer:
Its velocity changes
Explanation:
When the truck changes direction, its velocity changes.
Velocity is a vector quantity that specifies the magnitude of motion and direction it is taking.
When direction changes, the velocity of a body will also change. This is unlike speed which is a scalar quantity.
Velocity is the displacement divided by time taken.

A wave vibrates up and down 22 cycles in 7 seconds with a wave speed of 57. Calculate the
wavelength. (Round to the 2nd number after the decimal)
Answer:
18.14m
Explanation:
Given parameters:
Frequency = [tex]\frac{22}{7}[/tex]cycles/s
Speed of wave = 57m/s
Unknown:
Wavelength = ?
Solution:
The speed of a wave is related to frequency and wavelength using the expression below;
V = f x λ
V is the speed of the wave
f is the frequency
λ is the wavelength
Insert the parameters and find λ;
57 = [tex]\frac{22}{7}[/tex] x λ
λ = 57 x [tex]\frac{7}{22}[/tex] = 18.14m

A horse accelerates from rest for 1 s and covers a distance D. If instead the accelerates from rest with the same accelerations for 2 s will the distance it covers be equal to 2D, 4D, or 9D
Answer:
4D
Explanation:
We will use 2nd equation of motion in this question:
s = Vi t + (0.5)gt²
where,
s = distance covered
t = time taken
g = acceleration due to gravity
For t = 1 s:
s = D
Therefore,
D = (0 m/s)(1 s) + (0.5)g(1 s)²
D = 0.5g -------------- equation (1)
For t = 2 s:
s = D
Therefore,
s = (0 m/s)(1 s) + (0.5)g(2 s)²
s = 0.5g(4)
using equation (1):
s = 4D
therefore, correct answer is:
4D
