What voltage produces a current of 100 amps with a resistance of 50 ohms?
Answer:
To find the Voltage, ( V ) [ V = I x R ] V (volts) = I (amps) x R (Ω)
To find the Current, ( I ) [ I = V ÷ R ] I (amps) = V (volts) ÷ R (Ω)
To find the Resistance, ( R ) [ R = V ÷ I ] R (Ω) = V (volts) ÷ I (amps)
To find the Power (P) [ P = V x I ] P (watts) = V (volts) x I (amps)

Samuel's car has a mass of 3,000 kg. If your car produces a force of 500 N, how fast will it accelerate?
Answer:
The answer is 0.17 m/s²Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
[tex] a = \frac{f}{m} \\ [/tex]
f is the force
m is the mass
From the question we have
[tex]a = \frac{500}{3000} = \frac{5}{30 } = \frac{1}{6} \\ = 0.166666...[/tex]
We have the final answer as
0.17 m/s²Hope this helps you
A volleyball dug out by the opponent popped straight up into the air. It takes 2.05 seconds for the ball to reach its peak. Determine the height to which the ball flies. So far, I got the givens of t=2.05 seconds x=? a=9.8 meter per seconds squared final velocity=0 m/s they might be wrong though so help please!!!!
Answer:
The height to which the ball flies is 86.6 m.
Explanation:
Given that,
Time = 2.05 sec
Acceleration = 9.8 m/s²
We need to calculate the initial velocity of volleyball
Using equation of motion
[tex]v=u-at[/tex]
Where, u = initial velocity
a = acceleration
t = time
Put the value into the formula
[tex]0=u-9.8\times(2.05)^2[/tex]
[tex]u=41.2\ m/s[/tex]
We need to calculate the height of the the ball
Using equation of motion
[tex]v^2=u^2-2ah[/tex]
Put the value into the formula
[tex]0=(41.2)^2-2\times9.8\times h[/tex]
[tex]h=\dfrac{(41.2)^2}{2\times9.8}[/tex]
[tex]h=86.6\ m[/tex]
Hence, The height to which the ball flies is 86.6 m.
A physics student drops a water balloon from an upstairs window. The window is 26.45 m
from the ground. How long does it take for the balloon to hit the ground? (Round to the
nearest tenth)
Answer:
Explanation:
Given:
Distance S = 26.45m
Using the equation of motion
S = ut+1/2gt²
26.45 = 0+1/2(9.81)t²
26.45 = 4.905t²
t² = 26.45/4.905
t² = 5.392
t = 2.528s
Hence the it took the balloon 2.52s to reach the ground
A tennis ball, 0.384 kg, is accelerated at a rate of 187 m/s2 when hit by a professional tennis player. What force does the player's tennis racket exert on the ball?
Answer:
The answer is 71.81 NExplanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × accelerationFrom the question we have
force = 0.384 × 187 = 71.808
We have the final answer as
71.81 NHope this helps you
A helicopter takes off from the ground and rises vertically. It then hovers at a constant height above the ground. Which sequence of energy changes takes place during the gain in height?
Answer:
First the fuel in the engine gives chemical energy during burning. That chemical energy then converts to kinetic energy if the rotor of blades of the helicopter. Then kinetic energy converts in gravitational potential energy as it gains height.

A person jogs 4.0 km in 32 minutes, then 2.0 km in 22 minutes, and finally 1.0 km in 16 minutes. What is the jogger's average speed in km per minute?
Answer:
0.0928km/min (4dp)
Explanation:
To find the jogger's speed in km per minute, we just need to divide the number of km jogged by the time in minutes it took to jog that distance. This will give us the distance they jogged every minute which is their speed.
4km in 32 minutes:
4/32 = 0.125km/min
2km in 22 minutes:
2/22 = 0.091 (3dp)km/min
1km in 16 minutes:
0.0625km/min
Now to find the average speed of these 3 speeds, we just add them all together and divide by how many values there are (3 values).
Average (mean) = [tex]\frac{0.125+0.091+0.0625}{3}[/tex]
Average = 0.2785/3
Average speed of jogger = 0.0928 (4dp) km/min

If a mass of 10 kg is accelerated at a rate of 2 m/s^2, what force must be
applied?
Answer:
20N
Explanation:
10kg=mass 2m/s²= Acceleration
Force=?
the equation is;
Force(N)=Mass(kg) × Acceleration(m/s²)

Ren runs a hamburger stand and needs to clean up a season’s worth of grease buildup on the range hood over his griddle. explain what he should look for in a cleaning product that can handle a layer of grease
Answer:
A cleaning product that contains a base.
Explanation:
Ren should use a cleaning product that contains a base. This is because bases readily react with lipids (fats), the kind of compound that makes up grease. A base would break down the grease, forming soap, which would then easily wash away.

Joe follows the procedure below to make a compass. 1. Move a magnet from the top of a needle to its point fifty times. 2. Lay the needle on a cork that is floating in a bowl of water. 3. Observe the direction that the needle points. What is the purpose of step 1? to give the needle an electric charge to make the needle sharper to magnetize the needle to flatten the side of the needle
Answer:
C) To magnetize the needle
Explanation: I took the test!
When a magnet is moved away or towards a needle, current is bound to flow through the needle. The answer is to give the needle an electric charge.

What collides and creates a movement of heat called conduction?
A. photons
B. compounds
C. Molecules
D. atoms
Answer:
c.
Explanation:
Molecules collide and create a movement of heat called conduction.
What is conduction?
Conduction is defined as a process as a means of which heat is transferred from the hotter end of the body to it's cooler end.Heat flows spontaneously from a body which is hot to a body which is cold.
In the process of conduction,heat flow is within the body and through itself.In solids the conduction of heat is due to the vibrations and collisions of molecules while in liquids and gases it is due to the random motion of the molecules ,
When conduction takes place, heat is usually transferred from one molecule to another as they are in direct contact with each other.There are 2 types of conduction:1) steady state conduction 2) transient conduction.According to the type of energy conduction is of three types:
1) heat conduction
2) electrical conduction
3)sound conduction

Answer:

Explanation:
a. speed, distance , very large
What is a light year?Light-year is the distance light travels in one year. Light zips through interstellar space at 186,000 miles (300,000 kilometers) per second and 5.88 trillion miles (9.46 trillion kilometers) per year.
The speed of light measures the space traveled by electromagnetic waves every second.
In a vacuum, electromagnetic waves propagate at a constant velocity of approximately 299,792,458 meters per second.
In other words we can state that the speed of light refers to the rate that light travels through empty space.
Light-year is a unit of measurement used to calculate distances in astronomical space, i.e. where planets, stars, comets and so on are found.
The distances between the stars are huge, so to measure the immense dimensions of the universe requires the application of a special unit of measurement: the light year.
Because of this gigantic distance, the distance between the stars is measured in light years.
