Thank you for posting your question here at brainly. Below is the solution:

To find the circumference (orbit) of an object, you use Pi x Diameter.
As you have the circumference of B, you divide it by Pi to get the Diameter. 
So 120 divided by 3.141592654 = 38.2 minutes for the Diameter. 

As' radius and Diameter will be 3x greater than B. 
38.2 x 3 = 114.6 
To get back to the orbital period, times 114.6 by Pi, and you will get 360 minutes.

4. A crane has a weight of 85000 N and it rests on two caterpillar tracks which have a total

vagabundo [1.1K]

Answer:

50kPa and if the area decreases, the pressure increases

Explanation:

P=F/A; P=pressure, F=force, A=area

85000N/1.7 m^2 = 50000 N/m^2; Pa = Pascal = N/m^2

=50 kPa

What is the longest wavelength of radiation that possesses the necessary energy to break the o-o bond?

Vika [28.1K]

Answer:

The longest wavelength of radiation is 241nm and it lies in ultraviolet region.

Explanation:

The minimum energy required to break o-o bond is 495kJ/mole.

The photon does not have mass and the energy of the single photon depends entirely on the wavelength and is given by

e =hc/λ

where, h is the Planck constant,

c is the speed of light

e is the energy of photon

λ is the wavelength

From the Planck formula we can understand that energy of the photon is quantized.

E = e.Nₐ

e = E/Nₐ = $\frac{495KJ}{6.022*10^{23} }$ = 8.22*10⁻¹⁹ J/photon

λ = hc/E= $\frac{6.626*10^{-34}*2.998*10^{8} }{8.22*10^{-19} }$

λ = 2.41*10⁻⁷ m = 241 nm

The longest wavelength of radiation is 241nm and it lies in ultraviolet region.

A crowbar with the length of 200 cm is used to lift the load of 600 Newton . If the distance between fulcrum and load is 0.75 .

Leviafan [203]

Answer:

a. Effort = 960 Newton

b. Mechanical advantage (M.A) = 0.625

c. Velocity ratio (V.R) = 1.67

Explanation:

Given the following data;

Load = 600 N

Length of crowbar = 200 cm

Length of load arm = 0.75 m

Conversion:

100 cm = 1 m

X cm = 0.75 m

Cross-multiplying, we have;

X = 0.75 * 100 = 75 cm

First of all, we would find the effort arm;

Effort arm = length of crow bar - length of load arm

Effort arm = 200 - 75

Effort arm = 125 cm

Next, we would determine the mechanical advantage (M.A) of the crow bar;

Substituting the values into the formula, we have;

M.A = 0.625

To find the effort of the crow bar;

Making "effort" the subject of formula, we have;

Effort = 960 Newton

Lastly, we would determine the velocity ratio (V.R);

V.R = 1.67

PLEASE HEELP!!!

Ann [662]

Answer:

The "pressure" of the electricity is electric potential. Electric potential is the amount of energy available to push each unit of charge through an electric circuit. The unit of electric potential is the volt. ... A volt is the force needed to move one amp through a conductor that has 1 ohm of resistance
