A 70 n force pulls a box straight up 5 m above the ground. how much work is done on the box?

lord [1]

The work done on the box is 350 joules

Workdone can be described as the amount of energy transferred from an object.

Force can be described as the push on an object, this push makes the object to go through a change in velocity.

Distance can be described as the movement of an object towards any given direction.

It can be calculated by multiplying the force by the distance

Workdone= force × distance

= 70 × 5

= 350

Thus, the work done on the box is 350 joules

The speed of light in a piece of plastic is 1.87 × 10^8 meters per second. What is the absolute index of refraction of this plas

emmainna [20.7K]

Answer:

n = 1.6

Explanation:

The formula for the calculation of the absolute index of refraction is given as follows:

$n = \frac{c}{v}$

where,

n = index of refraction

c = speed of light in vacuum = 3 x 10⁸ m/s

v = speed of light in the piece of plastic = 1.87 x 10⁸ m/s

Therefore,

$n = \frac{3\ x\ 10^8\ m/s}{1.87\ x\ 10^8\ m/s}$

<u>n = 1.6</u>

A type of light bulb is labeled having an average lifetime of 1000 hours. It’s reasonable to model the probability of failure of

SashulF [63]

Answer:

$0.2592 \ or \ 25.92\%$

Explanation:

The exponential density function is given as

$f(t)=\left \{ {{0} \atop {ce^{ct}}} \right\\0,t$

$\mu=\frac{1}{c}\\c=\frac{1}{\mu}\\\\=\frac{1}{1000}=0.001\\\\f(t)=0.001e^{-0.001t}$

To find probability that bulb fails with the first 300hrs, we integrate from o to 300:

$P(0\leq X\leq 300)=\int\limits^{300}_0 {f(t)} \, dt\\\\=\int\limits^{300}_0 {0.001e^{-001t}} \, dt\\ =|-e^{-0.001t}| \ 0\leq t\leq 300$

$P(0\leq X\leq 300)=-0.7408+1\\=0.2592$

Hence probability of bulb failing within 300hrs is 25.92% or 0.2592

A reactor operating at 1 MW is scrammed by instantaneous insertion of $5.00 of negative reactivity. Approximately how long does

Novosadov [1.4K]

Answer:

time is 3333.33 min or 55.55 hr

Explanation:

given data

reactor operating = 1 MW

negative reactivity = $5

power = 1 miliwatt

to find out

how long does it take

solution

we know here power coefficient that is

power coefficient = $\frac{10^{6} }{10^{6} }$

power coefficient = 1

so time required to reach power is

power = reactivity × time / power coefficient + reactor operating

1 × $10^{-3}$ = -5 t / 1 + 1 × $10^{6}$

5t = $10^{6}$ - $10^{-3}$

t = 199999.99 sec

so time is 3333.33 min or 55.55 hr
