Is a violin and battery potential energy?
Explanation:
In physics, potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors. Common types of potential energy include the gravitational potential energy of an object that depends on its mass and its distance from the center of mass of another object, the elastic potential energy of an extended spring, and the electric potential energy of an electric charge in an electric field. The battery is storing the energy but give it something to power and it'll give its energy to the object and a violin strings are like ruber band and if you play the violin it releases a new type of energy sound energy.
Calculate the momentum of a boat with a mass of 95kg moving at 2m/Ss
Answer:
190 kg m/s
Explanation:
Momentum = Velocity × Mass
→ Substitute in values
2 × 95 = 190 kg m/s
The momentum of the boat of mass 95 Kg moving at 2 m/s will be 190 Kg m/s.
What is Momentum?Momentum is defined as the product of mass of velocity. Momentum is a vector quantity. Mathematically, we can write momentum as -
p = mv
It is also the measure of the impact force imparted by any moving object, when it comes in contact with some other body.
Given is a boat with a mass of 95 Kg moving at 2 m/s.
Mass [m] = 95 Kg
Velocity [v] = 2m/s
We can write the momentum as -
p = mv
Substituting values, we get -
Momentum [p] = 95 x 2 = 190 Kg m/s
p = 190 Kg m/s
Therefore, the momentum of the boat of mass 95 Kg moving at 2 m/s will be 190 Kg m/s.

If an engine can produce 670 J of energy in 1 min, how many watts can it output?
Answer:
11.2Watts
Explanation:
Given parameters:
Energy produced by the engine = 670J
Time taken = 1min = 60s
Unknown:
Number of watts it can output = ?
Solution:
This problem entails finding the power of the engine.
Power is the rate at which work is being done.
So;
Power = [tex]\frac{Work done }{time}[/tex]

A 2 cm object is 10 cm from a convex lens that has a focal length of 4.4 cm. The image is 8 cm from the lens.
The height of the image, to the tenths place, is
cm.
Answer:
-1.6
Explanation:
e2021
The Height of an Image for a Convex Mirror is calculated by using magnification equation
m = h(i) / h(o) = − d(i) / d(o) ,where
the magnification index of the mirror, m
the height of the object, h(o)
the height of the image, h(i)
the distance between the object and the mirror, d(o)
the distance between the image and the mirror, d(i)
h(i)/ 2 = -8 / 10
h(i) = -1.6 cm.
What is convex mirror ?"Convex Mirror is a curved mirror where the reflective surface bulges out towards the light source. This bulging out surface reflect light outwards and are not used to focus light."
What is magnification equation ?"The formula for magnification is m=h(i)/h(o)=-d(i)/d(o). m is the total magnification; h(i) is the height of the image; h(o) is the height of an object; d(i) is the distance from the lens to the in focus projected image; d(o) is the distance of the object to the lens. The negative sign represents that the image is inverted."

What is the cost of operating a 100 W light bulb for "4 hrs per day" for 30 days, if the cost of electricity is 6 cents kW•h
Answer:
the cost of operating the light bulb is 72 cents.
Explanation:
Given;
cost of electricity, C = 6 cents / kW.h
power of light bulb, P = 100 W
time of light power consumption, t = 4 hours per day for 30 days
total time = 4 hours x 30 = 120 hours
Power consumed by the light bulb is calculated as;
P = 100 x 120 = 12000 w.h = 12 kW.h
Cost of power consumption = 6 cents/kWh x 12 kWh
= 72 cents
Therefore, the cost of operating the light bulb is 72 cents.

7. An object with a weight of 19.6 N moves with a constant velocity of 20.0 m/s. A net
force of 6.00 N is applied to the object in the direction of its motion for 4.00 seconds.
What is the final momentum of the object?
Answer:
118.4kgm/s
Explanation:
Given parameters:
Weight of object = 19.6N
mass of object = 19.6/9.8 = 2kg
Constant velocity = 20m/s
Force applied = 6N
Time taken = 4s
Unknown:
Final momentum of the object = ?
Solution:
To solve this problem, we use Newton's second law of motion;
Ft = m (v - u)
F is the force applied
t is the time taken
m is the mass
v is the initial velocity
u is the time taken
Ft = mv - mu
mv is the final momentum;
So;
Final momentum = Ft + mu
Final momentum = (19.6 x 4) + (2 x 20) = 118.4kgm/s
