calculate capacitance if Q=7mc and delta V=12V
Answers
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

Answers
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

In which scenario does radiation occur? warming soup on a stove drying towels at the beach cooking eggs in boiling water warming a sore muscle with a hot pack
Answers
Answer: drying towels at the beach.
Explanation:
Radiation simply has to do with the energy that is gotten from a particular source and then goes through some materials. It simply means the way energy is being transmitted as waves or heat through a certain medium.
From the options given, the scenario whereby a radiation takes place is when drying towels on the beach.

You push on a light object (small mass) with a certain amount of force and it moves. If you push just as hard on a heavier object (large mass) it will move _____ the light object. a. Faster than b. slower than c. the same as
Answers
Answer: B
Explanation:
It will move slower than the light the object. The equation is Newton's 2nd Law of F = ma. If the force is constant, and the mass changes to something larger, then the acceleration must become smaller. You could also just do this yourself, push two objects with your hands. The heavier one will move slower assuming you used the same amount of force

Waves carry energy through empty space or through a medium without transporting matter. While all waves can transmit energy through a medium, certain waves can also transmit energy through empty space. A medium is a material through which waves can travel. It can be a solid, liquid, or gas.

TRUE or FALSE: An object's mass changes depending on which planet it is located.
A. TRUE
B. FALSE
Answers
Answer:
Fales
Explanation:
That's why scientists and engineers often measure an object's mass—how much matter the object contains—rather than its weight. Mass stays the same regardless of location and gravity. You would have the same mass on Mars or Jupiter as you do here on Earth. Your weight is different on other planets due to gravity.
Why does the layer of glass in a solar cell need an antireflective coating?

Two masses oscillating together with each of their time period as ,'T'
To find↷New time period ,'T'Answer↷Option B
Time period is independent of mass so it will remain same irrespective of the mass on the spring so the new time period would be the exact same as the previous one.Solution↷we know that,
The time period of a mass 'm' on a spring of spring constant 'k' can be strategize by the following equation :
[tex] \huge \rightarrow \: T \: = 2π \sqrt{ \frac{m}{k} } [/tex]
m⇢mass of the body [kg]k⇢spring constant [Nm^-1]According to the question,
The new mass would be 2mThe new spring constant would be 2kso,
The new time period would be
[tex] \huge \rightarrow \: T ' \: = 2π \sqrt{ \frac{2m}{2k} } [/tex]
[tex] \huge \rightarrow \: T ' \: = 2π \sqrt{ \frac{m}{k} } [/tex]
