40 N. If you’re using F=MA MxA would be 10x4 which would get you 40 N
Savatey [412]3 years ago

Answer:

Below

Explanation:

All we need to do for this question is to plug in our values and solve!

      Force = mass x acceleration

      Force = 10 kg x 4 m/s^2

     Force = 40 Newtons or 40 N

If your teacher requires you to round to sig figs it would be :

    F = 4 x 10^1 N

Hope this helps!

You do 45.0 joules of work and 3.00 seconds how much power do you use​
Arada [10]

Answer:

15 watt

Explanation:

Power is the rate at which work is done.

This means you divide the work done with the amount of time used to perform the work.

The formula for Power is : P = W/t  where;

W= work done in J = 45

t= time in seconds = 3 sec

P= 45/ 3 = 15 watt

A wire is used as a heating element that has a resistance that is fairly independent of its temperature within its operating ran
dedylja [7]

Answer:

Double the current

Explanation:

The energy delivered by the heater is related to the current by the following relation:

E= I^{2}R t

let R * t = k ( ∴ R and t both are constant)

so E= k I^{2}

Now let:

E2= k I₂^2

E2= 4E

⇒ k I₂^2= 4* k I^{2}

Cancel same terms on both sides.

I₂^2= 4* I^{2}

taking square-root on both sides.

√I₂^2 = √4* I^2

⇒I₂= 2I

If we double the current the energy delivered each minute be 4E.
