What is the terminal velocity of a 6.00-kg mass object in falling with a drag force with a magnitude that depends on speed, v, a

3241004551 [841]

When object reached the terminal speed then its acceleration is zero

So as per Newton's II law we can say

$F_{net} = 0$

now in that case we can say that net force is zero so here weight of the object is counter balanced by the drag force when it will reach at terminal speed

so we can write

$mg - F_d = 0$

so here we are given that

$F_d = 30$

$6*9.8 - 30*v = 0$

$58.8 - 30 *v = 0$

$v = \frac{58.8}{30}$

$v = 1.96 m/s$

so terminal speed will be nearly 2 m/s

Deduce the relation between kwh and joule define 1 watt

dimulka [17.4K]

Explanation:

We know that kWh is a commercial unit of energy.

Also, 1 Joule = 1 watt × 1 seconds

$1\ kWh=1kW \times 1\ h$

Since ,1 h = 3600 s and 1kW = 1000 W

$1\ kWh=1000\ W \times 3600\ s\\\\1\ kWh = 36\times 10^5\ W-s\\\\1\ kWh=36\times 10^5\ J$

So, the relation is : $1\ kWh=36\times 10^5\ J$

1 watt is defined as the power of an appliance when the energy is transferred at a rate of 1 Joule per second.

3. Suppose that you have an electrically charged stick. If you divide the stick in half, each half will have half the original c

FrozenT [24]

Answer:

No, you can't keep on dividing the charge forever.

Explanation:

No, you can't keep on dividing the charge in that manner forever because the total charge of the stick is an integer multiples of individual units known as an elementary charge, <em>which is the electron (e) charge (e = 1.602x10⁻¹⁹C)</em>.

Therefore the limit of the division of the original charge will be the electron charge since it is the smallest charge that can exist freely.

I hope it helps you!
