I REALLY NEED HELP!!!!

Physics
1 answer:
KIM [24]2 years ago
7 0

Answer:

The cans should move towards each other. This is due to Bernoulli's principle

that the air pressure will be reduced in the area between the cans. This is similar to lift on an airplane wing due to the faster moving air over the top of

the wing or the curving of a pitched baseball due to the rotation of the ball

causing greater air pressure on one side of the ball as compared to the air pressure on the other side of the ball.

The thermal energy used by heater in 3 minutes is used to melt wax.Melting point of solid wax is 60.Specific heat of wax is 220j
Romashka-Z-Leto [24]

Answer:

m = 35 g

Explanation:

The specific heat of a material can be calculated by the following formula:

C = \frac{Q}{m}\\

where,

C = Specific Heat of Wax = 220 J/g

Q = Amount of Heat Supplied by the Heater = 7700 J

m = mass of wax melted = ?

Therefore,

220\ J/g = \frac{7700\ J}{m}\\\\m = \frac{7700\ J}{220\ J/g}\\

<u>m = 35 g </u>

A 1.0 kg rock is thrown straight upward with an initial speed of 8.0 m/s. What is its speed
Ronch [10]

Answer:5.7m/s

Explanation:

Mass=1kg

Initial velocity=u=8m/s

height=h=1.6m

Final velocity =v

Acceleration due to gravity=g=9.8m/s^2

v^2=u^2-2xgxh

v^2=8^2-2x9.8x1.6

v^2=8x8-2x9.8x1.6

v^2=64-31.36

v^2=32.64

Take the square root of both sides

√(v^2)=√(32.64)

v=5.7

Speed at the height of 1.6m is 5.7m/s

Which compares the thermal energy found in a piece of coal with the thermal energy found in a newly opened coal mine?
9966 [12]

<span>The thermal energy found in a piece of coal is lesser than in the thermal energy in a newly opened coal mine. The newly opened coal mine requires a greater thermal energy to really open it due to its solid structure. Whereas in a piece of coal, it only requires a lesser amount of thermal energy to extract it.</span>

Albert is piloting his spaceship, heading east with a speed of 0.92 cc relative to Earth. Albert's ship sends a light beam in th
ohaa [14]

Answer:

He sees the light as 1c

Explanation:

According to relativity, the speed of light is the same in all inertial frame of reference.

If we were to add the velocities as applicable to a normal moving bodies, the relative speed of the light beam will exceed c which will break relativistic law since nothing can go past the speed of light.
