calculate capacitance if Q=7mc and delta V=12V
Answer:
Capacitance = 0.00058 Farads
Explanation:
Given the following data;
Charge, Q = 7mC to Coulombs = 7/1000 = 0.007C
Velocity = 12V
To find the capacitance;
Capacitance = charge/potential difference
Substituting into the equation, we have;
Capacitance = 0.007/12
Capacitance = 0.00058 Farads

Engineers at the Space Centre must determine the net force needed for a rockets engine to achieve an acceleration of 70 m/s2. Assume the rocket is in outer space with no gravitational or other forces acting on it. If the mass of the rocket is 45 000 kg, what force is required to be produced by the rocket engines?
Answer:
3,150,000N
Explanation:
According to Newton's second law;
F = mass * acceleration
Given
Mass = 45000kg
acceleration = 70m/s^2
Substitute
F = 45000 * 70
F = 3,150,000N
Hence the force required to be produced by the rocket engines is 3,150,000N
Answer:
3,150,000 Newtons
Explanation:
F=M*A
F=45,000kg times (*) 70 m/s squared
F=3,150,000N (newtons)

tony walks at an average speed of 70 m/min from his home to his school.If the distance between his home and the school is 2100 , how much time does it take for tony to walk to school
It takes 30 minutes for Tony to get to school.
2100 divided by 70 is 30, which would represent the amount of minutes.
Also he is walking very fast to be getting 70 in a minute.
Hope this helps and have a nice day.

According to Newton’s second law of motion, what is equal to the acceleration of an object?
Answer:. The acceleration of the object is directly proportional to the force and inversely proportional to the mass.
Explanation:
According to Newton s Second Law of Motion, also known as the Law of Force and Acceleration, a force upon an object causes it to accelerate according to the formula net force = mass x acceleration.

A. 0 m/s2
B. 7.3 x 104 m/s2
C. 0.1 m/s2
D.10 m/s2
Which kind of force(s) cause acceleration?
Answer:
unbalanced force,
Explanation:
The bigger the unbalanced force acting on the object the bigger the acceleration of the object. The more mass the object has, the more inclined it is to resist any change to its motion.

A 4.0 kg box is released from rest on a frictionless ramp. The box slides from the ramp onto a rough horizontal
surface with a friction coefficient per = 0.50. The box slides 2.0 m horizontally until it stops.
Answer:
0.99932188871837 rounded to 2 significant figures is 1.00m or 1.0m
Explanation:
Step 1 - First calculate the force with the formula: Force = mass × acceleration due to gravity/ (F=mg) {g= 9.8m/s²}
4.0kg × 9.8m/s² = 39.2 Newtons
Step 2 - Then calculate the Kinectic power with the following procedure:
Kinectic force = the coefficient of Kf × mg
0.50μ × 39.2 N = 19.6 Newtons of Kinectic force
Step 3 - Use the equation for Work that is = F×d; use the value of Kf and multiply it by the given distance
W = 19.6 N × 2.0m = 39.2 Joules of energy
↓Remember that the product of Work is Energy (W=E) and that in some cases, we can set W as = kinetic energy ( [tex]\frac{1}{2}[/tex]mass×velocity²) or as = gravitational potential energy (mass *acceleration due to gravity*height)
↑Since the unknown variable that we are told to find is 'height', let's use the second formula to help us solve the problem, where we said that GPE = mgh / PEg = mgh
Step 4 - Find the missing height using the formula, Energy gained from (W = mgh), by rewriting (mgh) to solve for h
39.2 J of E = 4.0kg × (9.8 m/s² × h)
h = [tex]\frac{PEg}{mg}[/tex]
h = [tex]\frac{39.2N}{9.8m/s{2} times 4.0kg}[/tex]
Height of box on-ramp = 1.0m

The can-chiller decreases the temperature of the liquid in the can by 15 °C.
The mass of liquid is 0.33 kg.
The specific heat capacity of the liquid is 4200 J / kg °C.
Calculate the energy transferred from the liquid as it cools.
Answer:
Energy transferred, Q = 20790 J
Explanation:
Given that,
The change in temperature of the liquid, [tex]\Delta T = 15^{\circ} C[/tex]
The mass of liquid, m = 0.33 kg
The specific heat capacity of the liquid is 4200 J/kg°C.
We need to find the energy transferred from the liquid as it cools. The energy transferred is given by :
[tex]Q=mc\Delta T\\\\Q=0.33\times 4200 \times 15\\\\Q=20790\ J[/tex]
So, 20790 J of energy is transferred from the liquid as it cools.
