Objects 1 and 2 attract each other with a gravitational force of 36.0 units. If the distance separating Objects 1 and 2 is changed to one-third the original value, then the new gravitational force will be units.
Answer:
324 units
Explanation:
Given that,
Objects 1 and 2 attract each other with a gravitational force of 36.0 units.
The distance separating Objects 1 and 2 is changed to one-third the original value.
Let the new force be F' and r'=r/3. so,
[tex]F=\dfrac{kq_1q_2}{r^2}[/tex]
[tex]F'=\dfrac{kq_1q_2}{r'^2}\\\\F'=\dfrac{kq_1q_2}{(\dfrac{r}{3})^2}\\\\=9\times \dfrac{kq_1q_2}{r^2}\\\\=9F\\\\=9\times 36\\\\=324\ \text{units}[/tex]
So, the new force become 324 units.

_____ is not a unit of pressure. *
A) armstrong
B) atmosphere
C) millimeter of mercury
D) Pascal
Answer:
A) Armstrong is not a unit of pressure. In fact, I don't think it's even a unit at all, an "Amstrong" is a unit of length, if that's what you meant.
Atmospheres, Millimeters of mercury, and Pascals are all units of pressure.

Solve for x and y algebraically:
x + y = 8 and 3x + 2y = 21
Explanation:
ans ...(5,3)..............
Answer:
x = 5
y = 3
Explanation:
x + y = 8 and 3x + 2y = 21
Here We use Substitution Method
x + y = 8 ...(1)
3x + 2y = 21 ...(2)
From equation (1) we get
x + y = 8
x = 8 - y
Now the value of x = 8 - y in equation (2)
3(8 - y) + 2y = 21
24 - 3y + 2y = 21
- y = 21 - 24
y = 3
Then Put the value of y in equation (1)
x + (3) = 8
x + 3 = 8
x = 8 - 3
x = 5
Thus The value of x is 5 and y is 3
For Verification Only:x + y = 8
5 + 3 = 8
8 = 8
3x + 2y = 21
3(5) + 2(3) = 21
15 + 6 = 21
21 = 21

If a constant fotce of 490 newtons is applied to an object and it proceeds to accelerate in the opposjte direction at 9.8 meters per second, every second, what is its mass?
Answer:
50 kg
Explanation:
f=ma
Force = mass x acceleration
490 = 9.8 x m
m = 50 kg
An object of mass 4.0 kg is dropped from a height of
1000 m from a helicopter. The air resistance acting
against the parachute exerts a steady upward force of 35 N. Calculate the kinetic energy of the object when it reaches the ground and hence find its velocity.

true or false if false correct the false statements :
a- the transformation of electric energy into themal energy is called joule's effect.
b - when a liquid is at rest , the pressure is at the same at any point within this liquid
Answer:
both statements are truth
Explanation:
a-The Joule effect, also called Joule's law, is the thermal manifestation of electrical resistance. ... In all these cases, it is intended to generate thermal energy with electricity passing through its conductors. This heat they give off is due to the Joule effect.
b-sure of a liquid tank depends only on the density of the liquid and depth from the free surface. It is a scalar quantity and is same in all directions, at a point.

Question
On a circular race track with a radius of 3.23 km, a
certain road car set a speed record of 372 km/h.
Complete Question:
On a circular race track with a radius of 3.23 km, a certain road car set a speed record of 372 km/h. What was the car's centripetal acceleration?
Answer:
Centripetal acceleration = 3.306 m/s²
Explanation:
Given the following data;
Radius, r = 3.23 km to meters = 3.23 * 1000 = 3230 m
Velocity = 372 km/h to meters per seconds = 372*1000/3600 = 103.33 m/s
To find the centripetal acceleration;
Centripetal acceleration = velocity²/radius
Centripetal acceleration = 103.33²/3230
Centripetal acceleration = 10677.09/3230
Centripetal acceleration = 3.306 m/s²
A battery of constant voltage is connected to a variable resistor. As the resistance of the resistor increases, what happens to the voltage? What happens to the current?
The electric current amount will vary according to the resistance value when connected to a voltage of a power supply. If resistance is reduced, current will increase. So, if the resistance is infinite (open circuit), the current could be considered zero, or infinitesimal small, if the resistance is zero (of infinitesimal small), the current will tend to be the maximum the power supply can provide. Here is the case of the power supply capability, input resistance, capacity to hold and regulate the output voltage to a certain maximum current, etc. Normally when you short circuit (zero ohms resi

A uniform steel girder of weight 22KN and of length 12m is lifted off the ground at one end by means of a crane. When the raised end is 2.0m above the ground, the cable is vertical.
A. Sketch a free-body diagram of the girder in this position
b. Calculate the tension in the cable at this position and the force of the girder on the ground
Answer:
Explanation:
For free body diagram see attached sheet .
W is weight of steel girder acting at the middle point of its length . T is tension in the cable .
OB = √ ( 12² - 2² )
= 11.83 m .
OC = 11.83 / 2 = 5.915 m
Taking moment of tension T and weight W about point O
W x OC = T x OB
22 x 5.915 = T x 11.83
T = 22 x 5.915 / 11.83
= 11 kN
Considering forces acting in vertical direction and equating forces in opposite direction
T + R = W
R = W - T
= 22 - 11 = 11 KN
So force of grinder on the ground = R
= 11 KN.
Can we have the Doppler effect with light waves? How?
Answer:
Besides sound and radio waves, the Doppler effect also affects the light emitted by other bodies in space. If a body in space is "blue shifted," its light waves are compacted and it is coming towards us. If it is "red shifted" the light waves are spread apart, and it is traveling away from us.

Answer:
the point the mass of an object will increase when traveling at relativistic speeds
Explanation:
m = m0/((1 - v2/c2))1/2
