Answer:

E; The object is negatively charged

Explanation:

Here, we want to state the conclusion that can be drawn from a positively charged rod being attracted to an object.

Generally as we know, oppositely charged materials attract while the ones with same charges repel each other.

Thus, in this case, for the rod to attract the object, there must have been an opposite charge of negativity on the object

So we conclude that the reason why the rod attracted the object was because of the presence of opposing charges on both of them. And since the rod has taken the positive charge, it is only correct to state that the object is negatively charged

What are muons in cosmology

yanalaym [24]

Answer:

Explanation:

Muons in the atmosphere, a component of cosmic rays. Atmospheric muons are an essential component of cosmic ray showers. When a high energy primary particle coming from space collides with a nucleus of the upper atmosphere, it generates a spray of particles which later interact in their turn.

Speed is velocity in a given direction<br> O True<br> O False

Zarrin [17]

Answer:

FALSE

Explanation:

Velocity = speed with direction.

Think of speed and direction like rockets and missiles. Rockets are not smart. Missiles are smart. Rockets go in one direction. Missiles can track their targets, they have a specific destination, a specific direction.

Velocity is often used in physics, because its almost useless to know how fast an object is going if you don't know which direction it is going.

Think of it like this. If the Weather man told you a hurricane was traveling at 30 miles an hour, but didn't tell you which direction it was going, you would have no idea where to run, or if it was going to hit you at all. However, if he told you it was going 30 miles an hour to the North, and you were West of it, you would be fine, and wouldn't have to worry.

If a person traveled from Sacramento to Los Angeles by car, their distance would be 384.9 miles. What would their displacement b

kumpel [21]

Answer:

Displacement from Sacramento to Los Angeles is 384.9 miles

Total path length is given as 769.8 miles

Displacement of complete round trip is ZERO

Explanation:

As we know that the displacement is the change in the position from initial to final in a straight line

Here we know that the car travel from Sacramento to Los Angeles

So the straight line distance between two is the displacement

so we have

displacement = 384.9 miles

Now we know that he returns from Los Angeles to Sacramento by same path

So total distance moved by it is same as total path length

d = 384.9 + 384.9

d = 769.8 miles

Also we know that initial and final positions are same so displacement is ZERO for complete round trip.

Consider a simple circuit. What can we do to make the bulb

Svetlanka [38]

Answer:

increase the resistance of the bulb

Explanation:

In a simple circuit the power dissipated in a light bulb is proportional to the product of the voltage and the current

P = i V

Besides the voltage is

V = i R

P = i² R

Therefore, a simple method to decrease the power dissipated in a bulb to increase the resistance of the bulb, for this a series resistance is placed in the circuit.

Consequently the correct answer is increase the resistance of the bulb
