Answer:

The acceleration is 36.5853659

Explanation:

Acceleration is the change in velocity over the amount of time so for this it would be 15ms/.41s so the acceleration would be 36.5853659m/s^{2}

Answer:

When you climb, earth exerts gravitational force on pack in downward direction(pointing towards the center of earth).

In order to climb, you need to work against work done by gravity on the pack.

Hence work done by you = work done by gravity on pack  

                                       = Force x displacement = 70 x 30 = 2100 J.

 

So you need to do 2100 joules of work to lift your pack.

Power is the rate of work done.

Therefore power = work done by you/time(in seconds)

                           =     2100/600 =3.5 watts

A horizontal force of 50 N is applied to the object.
USPshnik [31]

Answer:

Mass of object (m) = 5.102 kg

Explanation:

Given:

Horizontal Force (F) = 50 N

Find:

Mass of object (m) = ?

Computation:

We know that, acceleration due to gravity (g) = 9.8 m/s²

⇒ Horizontal Force (F) = mg

⇒ 50 N = m (9.8 m/s²)

⇒ Mass of object (m) =  50 / 9.8

⇒ Mass of object (m) = 5.102 kg

Mass of object (m) is 5.1 kg (Approx)

A current of 0. 82 a flows through a light bulb. how much charge passes through the light bulb during 94 s?
gladu [14]

A current of 0. 82A flows through a light bulb. The charge passed through the light bulb during 94 s is 77.08C

The amount of charge flown for a given period of time determines the current passed through a bulb or electrical body.

The relation between the charge, current and time is given as:

Q = I × t

where, Q is the charge flown through bulb

I is the current passed through bulb

t is the time for which charge passes through bulb

Given,

I = 0.82A

t = 94s

Q = ?

Substituting the values in the above formula:

Q = I × t

Q = 0.82 × 94

Q = 77.08C

Hence, The charge passed through the light bulb during 94 s is 77.08C
