Answer:

The gravitational potential energy (PE) of a particle or a system of particles is a form of energy that exists due to its position. Mathematically, it is expressed as the product of mass, gravitational acceleration, and the vertical displacement.

Explanation:

Given data:

Mass of the storage box, $m = 400.0 \ kg$

Height, $h = 10 \ m$

The gravitational potential energy of the storage box can be expressed as,

$PE = mgh$

$PE = 400.0 \times 9.80 \times 10$

$PE = 39200 \ \rm J.$

Answer: PE = 39,200 J

Explanation: Potential Energy can be calculated by using the formula

PE = mgh

= 400 kg ( 9.8 m/s² ) ( 10 m )

= 39,200 J

A scientist who conducted an experiment obtained an unexpected result. What will she most likely do with the unexpected result?

Kruka [31]

Answer: stop the experinment and begin again sometimes the result of the experiment may give you unexpected results due to the fact that you may have missed a certain step or you didn't follow the procedure accurately to the dot, hence it's important to redo the experiment and see if every step was followed accurately before you can discard the results or change the procedure.

A 1.70-μF capacitor is charging through a 14.0-Ω resistor using a 10.0- V battery. What will be current when the capacitor has a

RoseWind [281]

Answer:

The current is 0.951 A

Solution:

As per the question:

Capacitance of the capacitor, C = $1.70\mu F$

Resistance of the circuit, R = 14.0 $\Omega$

Voltage of the battery, V = 10.0 V

Now, when the charge become one-fourth of its initial value, the amount of current flowing is given by:

$q' = q(1 - e^{-\frac{t}{\tau}})$ (1)

where

q' = $\frac{q}{4}$

$\tau = RC$

$q' = q(1 - e^{-\frac{t}{RC}})$

$\frac{q}{4} = q(1 - e^{-\frac{t}{RC}})$

$0.25 = (1 - e^{-\frac{t}{RC}})$

$0.75 = e^{-\frac{t}{RC}$

$-\frac{t}{RC} = ln(0.75)$

$-\frac{t}{14\times 1.70\times 10^{- 6}} = - 0.2876$

$t = 6.844\times 10^{- 6} s$

Now,

The current is given by:

$I' = Ie^{-\frac{t}{RC}}$ (2)

Also, $I = \frac{V}{R} = \frac{10}{14} = 0.714 A$

Now, using the value of I = 0.714 A

$I' = 0.714e^{-\frac{6.844\times 10^{- 6}}{14\times 1.70\times 10^{- 6}}} = 0.951 A$

Explain why bicycles have gears in terms of the force-velocity property of muscle.

denpristay [2]

2 wheels force is put on the back gear to push a larger gear on front . when pedalling on flat force should be applied on middle to smaller size. However when bike reached a terminal force it rider will move to smaller gear and go faster. If bike is going down hill the force of gravity will mean rider can manage the smallest gear as in fastest speed as Force = Mass × Velocity and the impact of gravity means less force is required as the weight of the bike and rider However the opposite it through for uphill as the rider is going against gravity ..weight and gravity will mean the rider will need to go to the larger gear the slower speed.

There are other factors as in wind and slip stream and type of pedals to maximise the force.
