Which can do work faster-a 700 watt gasoline engine or a 300 watt electric motor

Physics
1 answer:
iogann1982 [59]3 years ago
3 0

"700 watts" means 700 joules of work per second.

"300 watts" means 300 joules of work per second.

If the labels on both machines are true, and both machines
are loaded to their full capacity, then the 700-watt engine
is doing work faster than the 300-watt one.

What is the electric flux ΦΦPhi through each of the six faces of the cube?
BlackZzzverrR [31]

Flux through each of the six faces of the cube: \frac{q}{6\epsilon_0}

Explanation:

In this problem, a charge q is placed at the center of the cube.

We can apply Gauss Law, which states that the flux through the surface of the cube is equal to the charge contained within the cube divided by the vacuum permittivity; mathematically:

\Phi_T=\frac{q}{\epsilon_0}

where

q is the charge

\epsilon_0 is the vacuum permittivity

Here we want to find the flux through each of the six faces of the cube.

By simmetry, we can say that the 6 faces are identical: therefore, the flux through each of them must be the same. This means that the flux  through each faces is 1/6 of the total flux through the total surface, therefore:

\Phi = \frac{1}{6}\Phi = \frac{q}{6\epsilon_0}

If you sleep 33% in a day, how many hours is that?
lesantik [10]

In this question, one has to carefully understand that the total number of hours in the day can never be more that 24 hours. based on this important fact the answer to the question can be very easily deduced. The only requirement is calculating perfectly.
Number of hours in a day = 24 hours
Percentage of hours of sleep in a day = 33%
Amount of sleep in the day = (33/100) * 24
                                             = 7.92 hours
So 33% of sleep in a day is equal to 7.92 hours. I hope this answer has helped you. In future you can keep the procedure in mind for solving such problems.
