What is the energy released from nuclear fuels inside a nuclear reactor used for

1 answer:

6 0

Each time a uranium nucleus splits<span> up it releases energy and three neutrons. If all the neutrons are allowed to be absorbed by other uranium nuclei the chain reaction will spiral out of control causing an explosion. To control the energy released in the reactor moveable control rods are placed between the fuel rods.</span>

Change into60f into c

Reil [10]

Answer:

15.6 C

Explanation:

Here we are given a temperature in Fahrenheit (F). We want to convert it into Celsius degrees (C).

The conversion can be done by using the following equation:

$T(C)=\frac{5}{9}(T(F)-32)$

where

T(C) is the temperature in Celsius degrees

T(F) is the temperature in Fahrenheit degrees

In this problem, we have

T(F) = 60 F

Therefore, by applying the equation,

$T(C)=\frac{5}{9}(60-32)=15.6 C$

What has to be true about mass if a small object (like a metal ball) has a high density? A: The mass has to be high compared to

inysia [295]

<span>Since density is equal to mass divided by volume, we can determine the relationship between mass, density, and volume. Therefore, we can automatically know that the answer must either be A or B, since this information is determinable. The prompt lists the object as small. Therefore, we know that density is high, but volume is low. Let's examine the equation (D = M/V), where d = density, m = mass, and v = volume. In order for any number to be divided by a smaller number and have the end result be a higher number, the numerator (i.e. mass) must be bigger than the denominator (i.e. volume). We can also see that this is true by substituting in somewhat random numbers for d, m, and v. D = M / V 5 = 10 / 2 10 > 2 M > V In conclusion, your answer is D.</span>

Ugo [173]

Answer:

0.08821 kgm²

Explanation:

f = Frequency = 1.7 Hz

m = Mass of lower leg = 5.7 kg

d = Distance of center of mass = 18 cm

g = Acceleration due to gravity = 9.81 m/s²

I = Moment of inertia

Frequency is given by

$f=\frac{1}{2\pi}\sqrt{\frac{mgd}{I}}\\\Rightarrow I=\frac{mgd}{(2\pi f)^2}\\\Rightarrow I=\frac{5.7\times 9.81\times 0.18}{(2\pi 1.7)^2}\\\Rightarrow I=0.08821\ kgm^2$

The moment of inertia of the lower leg is 0.08821 kgm²
