Answer : The correct option is, (A) Refrigerator

Explanation :

There are two type of current which are direct current (DC) and alternating current (AC).

Direct current : In this, the electric current or charge flows in one direction only.

Alternating current : In this, the electric current or charge changes in periodical direction. It is used to supply power to houses, office building, etc.

From the given options, refrigerator device is most likely used to operate on alternating current.

While the other options, flashlight, remote control and cell phone is used to operate on direct current. In these devices, a battery is used which is a source of direct current.

Hence, the correct option is, (A) Refrigerator

Which has greater mass of a bowling ball at rest for a rolling basketball which has greater momentum

IgorLugansk [536]

Answer:

The rolling basketball has greater momentum.

Explanation:

The momentum of an object is defined as the product of mass and velocity.

Given that the bowling mass has a greater mass than the basketball,

The bowling ball is at rest, so the velocity if the ball is zero.

The basketball is rolling, it has some velocity associated with it.

Therefore, the momentum of the bowling ball is zero.

The basketball has some momentum associated with it.

Hence, the rolling basketball has greater momentum.

A car travels 70 km in two hours 104 km in the next 1.5 hours and then 79 km in two hours before reaching its destination what w

stiks02 [169]

Average speed = (total distance) / (total time)

Total distance = (70km + 104km + 79km) = 253 km

Total time = (2hr + 1.5hr + 2hr) = 5.5 hrs

Average speed = (253 km) / (5.5 hrs)

<em>Average speed = 46 km/hr</em>

I need help on number 4 and 5

Strike441 [17]

4 is G. BB and Bb because that is what you are analyzing the product of.

5 is C. The round shape is obviously a dominant trait since mixing with a wrinkled shape didn't have an effect. The wrinkled shape is recessive.

Does a battery produce electric currents?

Leokris [45]

Answer:

A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit. The flow of electrons provides an electric current that can be used to do work.
