Answer:

The first factor is the amount of charge on each object. The greater the charge, the greater the electric force. The second factor is the distance between the charges. The closer together the charges are, the greater the electric force is.

Natalka [10]

Answer:

$EMF = 1684.67 Volts$

Explanation:

As we know that EMF is induced in a closed conducting loop if the flux linked with the loop is changing with time

So we can say

$EMF = \frac{d\phi}{dt}$

now we have

$\phi = BA$

here since magnetic field is constant so we have

$EMF = A\frac{dB}{dt}$

now we have

$A = (190 \times 10^3)(190 \times 10^3)$

$A = 3.61 \times 10^{10} m^2$

now we have

$EMF = 3.61\times 10^{10} (\frac{2.8 \times 10^{-6}T}{60 s})$

$EMF = 1684.67 Volts$

Answer:

v=38.73m/s

Explanation:

u=15m/s

v =?

s=65m

g=9.81

v²=u²+2×g×s

v²=15²+2×9.81×65=1500.3

v=38.73m/s

Usain Bolt's world-record 100 m sprint on August 16, 2009, has been analyzed in detail. At the start of the race, the 94.0 kg Bo

kifflom [539]

Answer:

893 Newtons

Explanation:

m = Mass of Usain Bolt = 94 kg

a = Acceleration of Usain Bolt in the first 0.89 seconds = 9.5 m/s²

From Newton's Second law

Force

$F=ma$

$\\\Rightarrow F=94\times 9.5$

$\\\Rightarrow F=893\ N$

The average horizontal force exerted by Bolt against the ground during the first 0.890 s of the race is 893 Newtons

A baseball player throws a baseball at 42 m/s. If the other player catching the baseball is 18 m from the player, how much time

Hitman42 [59]

Divide the distance by the speed:

(18 m) / (42 m/s) = 3/7 s ≈ 0.43 s

Water ______________ easier in the mountains because there is less air pressure.

Alchen [17]

<h3>Answer: 1) Boils</h3>

The less air pushing down on the water effectively allows the water to boil easier. Think of the water molecules as a bunch of marbles bouncing around in a box with a lid. The less air pressure means the lid is easier to open from the force exerted by the bouncing marbles, allowing those particles to escape and turn into gas.

So in short, if you are in the mountains, then it'll take less time to cook food because water comes to a boil faster.
