what factors affect electrostatic force?
Answer:
The first factor is the amount of charge on each object. The greater the charge, the greater the electric force. The second factor is the distance between the charges. The closer together the charges are, the greater the electric force is.

Ted lifts a 10N weight at a height of 1.5 m in 1 second. Johnny lifts a 10N weight at a height of 1.5 m in 2 second. Which statements are correct? A. Johnny and Ted did the same amount of work B. Ted did more work C. Johnny and Ted expanded the same power D. Ted expanded more power E Johnny did more work F. Johnny expanded more power
Answer:
he affirmations the correct ones are: A and D
Explanation:
To find out which expressions are correct, let's calculate the work and power done by each person
the expression for work is W = F and
the expression for power is P = W / t
In this case the work is positive because the beast is in the same direction of displacement.
Ted
W₁ = 10 1.5
W₁ = 15 J
P₁ = 15/1
P₁ = 15 w
Johnny
the job
W₂ = 10 1.5
W₂ = 15 J
the potential
P₂ = 15/2
P₂ = 7.5 w
therefore we see that the work of both is the same, but Ted developed twice as much power as Johnny
when resisting the affirmations the correct ones are: A and D
Camina con otro compañero, al mismo tiempo y al mismo paso. Quién se mueve tú o tu compañero? Razona tu respuesta
Answer:
Fricción.
Explicación:
Caminando con otro compañero al mismo tiempo y al mismo ritmo, el movimiento se produce debido a la fricción del suelo y la suela de los zapatos porque la fricción es la fuerza que ayuda en el movimiento de los objetos de un lugar a otro. Si no hay fricción entre el suelo y la suela de los zapatos, no podemos dar un paso por lo que podemos decir que la fricción nos mueve hacia adelante.

A 50 kg boy jumps off the front of a 1.5 kg skateboard moving forward. Find the skateboard's velocity
immediately after the boy jumps, assuming that the skateboard's initial velocity is 3.5 m/s and the boy's
velocity when jumping off the front is 5 m/s?
Answer:
The speed is 1.35 m/s
Explanation:
(m1+m2) vi= m1+m2v2
(50+1.5) (3.5)=50 (5+v2) +1.5 v2
180.25= 250+ 51.5 v2
180.25- 250+ 51.5 v2
-69.75= 51.5 v2
v2= -1.35 m

Explanation:
If a car has a velocity of 85 km/hr, how long will it take to accelerate to 45 km/hr if the acceleration is -3 km/hr/sec?
Answer:
Time, t = 13.34 seconds.
Explanation:
Given the following data;
Initial velocity, u = 85km/hr to meters per seconds = 85*1000/3600 = 23.61 m/s
Final velocity, v = 45km/hr to meters per seconds = 45*1000/3600 = 12.5 m/s
Acceleration, a = -3 km/hr/sec to meters per seconds square = -3*1000/3600 = -0.833m/s²
To find the time;
Acceleration = (v - u)/t
-0.833 = (12.5 - 23.61)/t
-0.833t = -11.11
t = 11.11/0.833
Time, t = 13.34 seconds.
Which do you think requires more Work, lifting a 100 N load a vertical distance of 2 m or lifting a 10 N load a vertical distance of 4 m?
Answer:
Lifting 100 N 2 meters is much more work.
Explanation:
Remark
The formula is F * d = W
Givens
F = 100 N
D = 2 m
or
F = 10 N
D = 4 m
Solution
Work = 100 * 2
Work = 200 Joules
Work = 10 * 4
Work = 40 J

If the force causing a mass to accelerate is multiplied by a number while keeping the mass the same, what happens to the acceleration of the object?
Answer: If mass remains constant and you double the force you will double the acceleration.

If a vehicle accelerating at 2.7 m/s2what is it's velocity at 20 meters 12.63m/s,1.03m/s,10.39m/s,6.39m/s
Answer:
The final velocity of the vehicle is 10.39 m/s.
Explanation:
Given;
acceleration of the vehicle, a = 2.7 m/s²
distance moved by the vehicle, d = 20 m
The final velocity of the vehicle is calculated using the following kinematic equation;
v² = u² + 2ah
v² = 0 + 2 x 2.7 x 20
v² = 108
v = √108
v = 10.39 m/s
Therefore, the final velocity of the vehicle is 10.39 m/s.
Two people travel from Columbus to Cleveland, one by car at an average velocity of 90km/h, and one by plane at an average velocity of 300km/h. Can their displacements be equal
Answer:
Explanation:
Yes , their displacement may be equal .
Suppose the displacement is AB where A is starting point and B is end point .
The car is covering the distance AB by going from A to B on straight line . On the other hand plane goes from A to C , then from C to D and then from D to B . In this way plane reaches B from A on a different path which is longer than path of the car . In the second case also displacement of plane is AB . In the second case distance covered is longer but displacement is same that is AB .

Why did you need a permanent magnet? What do you think would happen if you increased the
number of permanent magnets? (dc motor)
Permanent magnets are important for their industrial uses especially when it comes to power generation and electric motors. The induction process for turbines and generators needs permanent magnets to turn mechanical motion into energy.
Exposing magnetized magnets to opposing external fields produces a demagnetizing effect. This effect is most apparent in permanent magnet materials having a non-linear demagnetization curve, such as Alnico. ... Other factors such as SHOCK and VIBRATION have very little effect on today's permanent magnet materials.
A)This part controls the amount of light entering the eyes. A= Iris B= Pupil Give reason for your answer.
Answer:
Iris
Explanation:
Iris can be described as a part of the eyes which regulates the amount of light that enters the eye. The iris is made up of various muscles that control the size of the pupil
When a person is in a well-lighted room, the iris decreases the size of the pupil so that a low amount or medium amount of light is absorbed into the pupil. Also when an individual steps into a dark room the iris increases the size of the pupil so that a high amount of light penetrates the pupil.
Hence without the iris the amount of light that enters the eye cannot be controlled.
