The emf power supply should be used for a 0.75 A recharging current is 2.25 V.

<h3>What is current?</h3>

The current is the stream of charges which flow inside the conductors when connected across the end of voltage.

Given is the battery having 1.5 V open circuit potential and internal resistance of 1 ohm.

From the Ohm's law, V =IR

R = V/I

Here, R is the proportionality constant.

To charge current I = 0.75 A

Voltage V = 0.75A x 1 ohm = 0.75 V

Total potential required is

= 1.5 +0.75

= 2.25 V

Thus, the emf power supply should be used for a 0.75 A recharging current is 2.25V.

What must happen to an object in order to accelerate it?

White raven [17]

Answer:

For an object to accelerate, appropriate force must be applied to the object to cause it to change it’s velocity if it’s already in motion. However, to cause it to overcome static friction if it is at rest, and cause it to change it’s velocity

Equipotential lines are usually shown in a manner similar to topographical contour lines, in which the difference in the value o

Anna35 [415]

Answer:

the correct one is 2. the equipotential lines must be closer together where the field has more intensity

Explanation:

The equipotential line concept is a line or surface where a test charge can move without doing work, therefore the potential in this line is constant and they are perpendicular to the electric field lines.

In this exercise we have a charge and a series of equipotential lines, if this is a point charge the lines are circles around the charge, where the potential is given by

V = k q / r

also the electric field and the electuary potential are related

E = $- \frac{dV}{dr}$

therefore the equipotential lines must be closer together where the field has more intensity

A- what constant acceleration, in SI units, must a car have to gofrom zero to 60 mph in 10 s?

umka2103 [35]

Answer:

(a) 0.017m/s^2

(b) 17/100,000

Explanation:

(a) speed = 60mph = 60m/1h × 1h/3600s = 0.017m/s, time = 10s

Acceleration (a) = speed ÷ time = 0.017m/s ÷ 10s = 0.0017m/s^2

(b) g = 9.8m/s^2, a = 0.0017m/s^2

a/g = 0.0017/9.8 = 0.00017 = 17/100,000

A cable weighing 0.6 pounds per foot is attached to a small 70-pound robot, and then the robot is lowered into a 50-foot deep we

Sav [38]

Answer:

4600 ft.Ibs

Explanation:

Work done by the robot in climbing to the top of the well = work done in carrying the cable and itself + work done in carrying about average half the mass of the cable attached to the robot

Now work done = Force × distance = (( 70 +7 ) × 50 ft) + (( 0.6 × 50 ft) × 25 ) = 3850 + 750 = 4600 ft.Ibs

Give an example of a collision in real life. Use the law of conservation of energy to describe the transfer of momentum. Be sure

ozzi

Explanation :

Using the law of conservation of energy

When two cars collide with each other then the momentum is same before collision and after collision but energy is changed after collision in form of heat and sound.

We know this collision is inelastic collision.

In Inelastic collision, when two objects collide with each other then the momentum is conserved but kinetic energy is not conserved.
