Answer:

Frictional force always acts parallel to two planes in contact with each other and in a direction opposite to that of relative motion of the two bodies. 2. Frictional forces are caused due to intermolecular interactions between the bodies.  Frictional force is more for rough surface and less for smooth surfaces.

Two light bulbs are installed in two sockets, the sockets are connected in series, and power is then applied to the combination
Arisa [49]

Answer:

False

Explanation:

<em>If one of the bulbs is removed from the series, the other bulb will not come on at all.</em>

This is because the removal of one of the bulbs would interrupt the flow of current though the entire circuit.

Hence, that the other one will get brighter if one of two bulbs in a circuit is removed from its socket is not true.

What is the term for the principal that an object in motion remains in motion until it is met by an outside force?
Papessa [141]

The term for the principal that an object in motion remains in motion until it is met by an outside force is called inertia

Newton's first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force .This principal is named as inertia .

Every matter have inertia , a property to remain in that very position until unless it is been forced on them to change their position .

Inertia is a property of matter that causes it to resist changes in velocity (speed and/or direction). According to Newton's first law of motion, an object with a given velocity maintains that velocity unless acted on by an external force. Inertia is the property of matter that makes this law hold true.

A light bulb operating at a voltage of 120 v has a resistance of 200 ω. what is the power?
cluponka [151]

The correct is 72 watt

We know that formula of power is P=\frac{v^{2} }{r}

so putting the value of Voltage and Resistance in Formula of power so we get

P=\frac{120^{2} }{200} =72

What is Power?

Electric power is the rate at which an electric circuit transfers electrical energy per unit time.

Typically, electricity is generated by generators, but it can also be supplied by sources such as electric batteries. The electric power industry typically distributes it via an electric power grid to businesses and homes (as domestic mains electricity).

Transmission lines allow electric power to be delivered over long distances and used for high-efficiency applications such as motion, light, or heat.  Electric charges are converted to other forms of energy when they pass through an electric potential difference (voltage).

What kinds of information does the ALMA radio telescope provide?
zimovet [89]

Answer:

ALMA is a trans-formative radio telescope that can study cosmic light that straddles the boundary between radio and infrared. Most objects in the Universe emit this kind of energy, so the ability to detect it has been a driver for astronomers for decades.
