A certain car engine delivers enough force to create 630 N⋅m of torque when the engine is operating at 3200 revolutions per minu
jekas [21]

The appropriate expression for the calculation of power by relating the angular energy in a given time.

In other words the instantaneous power of an angular accelerating body is the torque times the angular velocity

P=\tau\omega

Where

\tau = Torque

\omega =Angular speed

Our values are given by

\tau = 630Nm

\omega = 3200rev/min

The angular velocity must be transformed into radians per second then

\omega = 3200rev/min (\frac{2\pi rad}{60s})

\omega = 335.103rad/s

Replacing,

P=(630)(335.103)

P = 211.11*10^3W

P = 211.1kW

The average power delivered by the engine at this rotation rate is 211.1kW

At present, NASA is planning a mission to Europa, to try and assess its habitability. An argument might also be made for Encelad
kifflom [539]

Answer:

Jupiter

Explanation:

For this space trip, the distance to the planet must be taken into account, so Because Jupiter is much closer it should be the correct choice

.

It must also be taken into account that Saturn has a series of rings, for which the ship has a probability of colliding with one of these in one of its turns, therefore taking this into account, Jupiter must also be chosen.

Matter that does not transmit any light.
eduard

Answer:

They all travel at the same speed

Explanation:  the speed of light — in a vacuum, but when they come into contact with matter, they slow down. ... Opaque objects transmit little or no visible light, translucent objects transmit some, and transparent objects transmit almost all, which is why we can see through them.
