Answer:

50,000 joules

50kJoules

Explanation:

F = m * a

here, m = 100kg. a = 10m/s^2

F = 100 * 10

= 1000 Newtons

Here, d= 50m. F = 1000newtons

W = F * d

= 1000 * 50

= 50,000 joules

= 50 kilo joules

Answer:

20 joule is your answer

Answer:

here

mass m =100kg

distance d=50m

acceleration due to gravity a =10m/s²

work =force×displacement

= ma/d=100×10/50=20joule

torisob [31]

Answer:

$\omega_s=12.8886\ rad.s^{-1}$

Explanation:

Given that:

moment of inertia of tucked body, $I_t=16\ kg.m^2$

rotational speed of the body, $N_t=2.5\ rev.s^{-1}$

i.e. $\omega_t=2\pi\times 2.5=15.708\ rad.s^{-1}$

moment of inertia of the straightened body, $I_s=19.5\ kg.m^2$

<u>Now using the law of conservation of angular momentum:</u>

angular momentum of tucked body=angular momentum of straight body

$I_t.\omega_t=I_s.\omega_s$

$16\times 15.708=19.5\times \omega_s$

$\omega_s=12.8886\ rad.s^{-1}$

What is the sentence that we use to<br> remember how to convert metric<br> prefixes?

Marrrta [24]

Answer:

The mnemonic I can use to memorize the metric prefixes in this order is: Gigantic Monsters Killed One Million Men Napping Peacefully. All right, so again, gigantic monsters killed one million men napping peacefully.

A student slides her 80.0-kg desk across the level floor of her dormitory room a distance 4.00 m at constant speed. If the coeff

zysi [14]

Answer:

Work done is equal to 125.44 J

Explanation:

We have given mass of the student m = 80 kg

Distance moved d = 4 m

Acceleration due to gravity $g=9.8m/sec^2$

Coefficient of kinetic friction $\mu =0.4$

So normal force exerted by student $F=\mu mg=0.4\times 80\times 9.8=313.6N$

We know that work done is equal to multiplication of force and distance

So work done $W=Fd=313.6\times 0.4=125.44J$

There is a box on the floor. The following forces are being applied to it:

Sergio [31]

The answer is 6.

Add 4 then divide 2. You should have 18 after you do that, subtract 10 then multiply 20. You then have 6.
