If you have a projectile and you double its mass, how would this affect its horizontal velocity?

Answers

Answer 1

Answer:

Its horizontal velocity is determined at the instant of launch ... the angle and speed with which you launch it.

I suppose its mass might have some influence on how fast and at what angle you launch it, but we'd have to know more about how strong you are, and how you throw, to know what the effect of the mass might be.

But that's still just the effect the mass has on YOUR ability to handle it. If we can assume that you launch every projectile at the same angle and with the same speed, then their different masses have no effect on their range. Every projectile you launch hits the ground at the same place. Mass makes no difference.

What is the apparent magnitude of the brightest star in the Big Dipper?

Answers

Answer: +1.77

Explanation:

Big dipper is the asterism made of seven bright stars in Ursa Major constellation. An asterism a pattern formed by joining the bright stars in the night sky. On the other hand, whole night sky is divided into 88 areas called constellations. These asterisms are used to identify the constellations.

The brightest star of the big dipper is Alioth which is the 32nd brightest star in the night sky. Its apparent magnitude is +1.77.

The magnitude of Alioth ( the brightest star in the big dipper ) is 1.76 and it is about 81 light years distant from Earth.

What is the acceleration of a ball traveling horizontally with an initial velocity of 20 meters/second and, 2.0 seconds later, a velocity of 30 meters/second?

Answers

The acceleration of the ball is 5 m/s^2. This can be calculated using a formula that relates the change in velocity, acceleration, and time. This formula is:

Vf = Vi + at

where:
Vf = final velocity
Vi = initial velocity
a = acceleration
t = time

Substituting the values gives:

30 = 20 + a(2)
a = 5 m/s^2 --> Final Answer

Answer:

5.0 meters/second^2

Explanation:

A series circuit contains four light bulbs. The switch is opened and one of the bulbs is removed, but not replaced. Then the switch is closed again. What would you expect to see?A) All three remaining light bulbs will be on.
B) None of the remaining light bulbs will be on.
C) Only the bulb closest to the switch will be on.
D) All three remaining light bulbs will be brighter than before.

Answers

The correct answer is option B) None of the remaining light bulbs will be on.

What will happen if one light bulb is removed from a series circuit?

In a series connection when a bulb is removed, it will be creating a open circuit. Since the circuit is series and is open at a point current will not flow and hence the other bulb will not glow.

Why did the series circuit stop working when one of the light bulbs was removed?

That's because the basic requirement for the circuit to operate a continuous, closed-loop path is no longer met. This is the main disadvantage of a series circuit. If any one of the light bulbs or loads burns out or is removed, the entire circuit stops operating.

#SPJ

for series circuit, components are in the same path. removing component, the path is broken. so without replacing the bulb, current could not flow -- open circuit. all bulbs are dead.

The output of a solar panel powers a small pump. The pump operates a garden water fountain. The output of the solar panel is 10 V and the current supplied to the pump is 0.25 A. Calculate the electrical power generated by the solar panel.

Answers

The power generated by solar panel will be "2.7 W".

According to the question,

The values are:

Output of solar panel,

10 V

Current,

0.25 A

The electrical power generated will be:

→ $P = VI$

By substituting the given values is the above formula, we get

→ $= 10* 0.27$

→ $=2.7 \ W$

Thus the above answer is right.
