URGENT PHYSICS QUESTION WILL GIVE BRAINLIEST
Morgarella [4.7K]

Answer:

7.2V

Explanation:

Find the equivalent resistance:

Req = 10 ohms + 15 ohms = 25 ohms

Use ohm's law to find the current:

V = IR

12V = I(25 ohms)

I = .48 amps

Multiple the current with the value of R2 to get the voltage drop:

.48amps x 15 ohms = 7.2V

An object in a fluid experiences a buoyant force from the fluid. If the object is completely immersed, on which does the magnitu
loris [4]

Answer:

Weight of the fluid that the object displaces.

Explanation:

When the fluid is completely immersed in a fluid, it experiences pressure from all the direction. While the object is immersed in the fluid a force acts on it in the opposite direction, i.e., upwards. This force is termed as buoyant force.

Also, as per the Archimedes' Principle, the force experience by the object is the same as the weight of the fluid that gets displaced by the object.

Thus on complete immersion of the object in the fluid, it experiences the force same as the weight of the fluid that gets displaced

1. Why should you use scientific notation when writing big numbers?
Fynjy0 [20]

Answer:

It helps the answer look clean. It also makes the work easier to work with.

Explanation:

Instead of writing a lot of zeros, all you have to do is add exponents to the number to show how much the decimal moved.

A Smart Car, which has a mass of 1000 kg, is going 20 m/s. When it hits the barrier, it stops with a time of 0.5 seconds. What i
antiseptic1488 [7]

Answer:

The change in momentum = -20000 kg m/s.

Explanation:

Mass m = 1000 kg

speed v₁ = 20 m/s

speed v₂ = 0 m/s

We know that,

The change in momentum

ΔP = m (Δv)

ΔP = m (v₂ - v₁)

     = 1000 (0 - 20)

     = 1000 (-20)

     = -20000 kg m/s

Thus, the change in momentum = -20000 kg m/s.

Note: negative sign indicates that the velocity is reducing when it hits the barrier.
