The balanced nuclear reaction is shown by the following: ²³⁷₉₃ Np[tex]\rightarrow[/tex]⁴ ₂He +²³³₉₅ Am nuclear fission reaction.
What are nuclear reactions?There are two types of nuclear reactions which are nuclear fusion and nuclear fission .They involve the combination and disintegration of the element's nucleus respectively.
In nuclear fission, the nucleus of the atom is bombarded with electrons of low energy which splits the nucleus in to two parts .Large amount of energy is released in the process.It is used in nuclear power reactors as it produces large amount of energy.
In nuclear fusion,on the other hand, is a reaction which occurs when two or more atoms combine to form a heavy nucleus.Large amount of energy is released in the process which is greater than that of the energy which is released in nuclear fission process.

what is aerobic activities
Answers
Answer:
Aerobic exercise is any type of cardiovascular conditioning. It can include activities like brisk walking, swimming, running, or cycling. You probably know it as “cardio.”
By definition, aerobic exercise means “with oxygen.” Your breathing and heart rate will increase during aerobic activities. Aerobic exercise helps keep your heart, lungs, and circulatory system healthy.
Aerobic exercise differs from anaerobic exercise. Anaerobic exercises, such as weightlifting or sprinting, involve quick bursts of energy. They’re performed at maximum effort for a short time. This is unlike aerobic exercises. You perform aerobic exercises for a sustained period of time.
Explanation:
Aerobic exercise is physical exercise of low to high intensity that depends primarily on the aerobic energy-generating process. "Aerobic" is defined as "relating to, involving, or requiring free oxygen", and refers to the use of oxygen to adequately meet energy demands during exercise via aerobic metabolism

Kellie is hopping on one foot. Kellie has a mass of 650
newtons and her foot has an area of 0.10 m2.
How much pressure is exerted by her foot on the ground
with each hop?
Answers
Answer:
650 N / 0.10 m2 = 6500 Pa
Explanation:
The pressure that could be exerted on the ground with each top should be 6,500 Pa
Given that,
The mass is 650 newtons.The area should be 0.10m^2We need to determine the pressure.
So, the following formula should be used.
[tex]= \frac{Mass}{area}\\\\= \frac{650}{0.10} \\\\[/tex]
= 6,500 Pa
Therefore we can conclude that the pressure that could be exerted on the ground with each top should be 6,500 Pa.

Explanation:
1/2 means that the voltage (or charge) of the system will increase to half more of what is left in a time equal to t1/2 seconds. Therefore if a system is already at half charge (t1/2 seconds after starting) then after t1/2 more seconds the system will be charged to 50% plus half of 50%. That is 25% more, or 75% of the entire charge. Let's say that four t1/2's have gone by. That means that the charge (or voltage) is at (50% + 1/2*50% + 1/2*1/2*50% + 1/2*1/2*1/2*50%) = 93.75% of maximum charge. Yikes! Now look in your manual for a more simple mathematical derivation of this concept. Given t1/2 to be 0.4406 seconds, how long should it take to reach 75% of maximum charge? answer in seconds.
Answers
Answer:
The answer is "0.047".
Explanation:
Given value:
[tex]\to t_{\frac{1}{2}}= 0.4406\\\\\to V=0.9375 V_{max}[/tex]
Calculating the capacitance:
[tex]\to V=V_{max} (1-e^{\frac{-t}{Rc}})[/tex]
In this, the t = time, which is taken to calculates its maximum voltage.
[tex]\to 0.9375 V_{max} = V_{max}(1-e^{- \frac{t}{103\times(165.279\times10^{-6})}})\\\\\to e^{- \frac{t}{103\times(165.279\times10^{-6})}}= 0.0625\\\\\to - \frac{t}{103\times(165.279\times10^{-6})} = \ln(0.0625)\\\\\to -t= 0.01702\times(-2.77258) \\\\ \to -t = -0.04719 \\\\ \to t= 0.04719 \approx 0.047 \ s[/tex]

Does the mass of the objects you are charging influence the amount of electric force created in an electric field?
Answers
Explanation:
Both gravitational and electric forces decrease with the square of the distance between the objects, and both forces act along a line between them. In Coulomb's law, however, the magnitude and sign of the electric force are determined by the electric charge, rather than the mass, of an object.
A skier skies down a slope with an average speed of 50 km/s. How far does the skier travel in 5 minutes?
Answers
Answer:
15000000 m
Explanation:
From the question,
Speed (S) = Distance(d)/Time(t)
S = d/t....................... Equation 1
Make d the subject of the equation
d = St..................... Equation 2
Given: S = 50 km/s = 50000 m/s, t = 5 minutes = 5*60 seconds = 300 seconds
Substitute these values into equation 2
d = 50000(300)
d = 15000000 m
Hence the skier travels 15000000 m
2. A compressed gas is held inside a canister with a moveable lid. The temperature of the gas is significantly
higher than the air temperature outside the canister. When weight is removed from the lid, the gas
expands to lift it. For this expansion to be as nearly adiabatic as possible, which condition should be met?
Answers
Answer:
Heat supplied should be equal to zero.
Explanation:
Given that a compressed gas is held inside a canister with a moveable lid. The temperature of the gas is significantly higher than the air temperature outside the canister. When weight is removed from the lid, the gas
expands to lift it.
For this expansion to be as nearly adiabatic as possible, one of the conditions that should be met is that there should be no supply of thermal or heat energy to the system.
According to first law of thermodynamics:
Change in internal energy = heat supply + work done by the system
If heat supplied = 0
Then, nothing is constant.
The internal energy = work done by the system.
Therefore, no heat should be supplied to the system.

Final momentum after a head on collision is -2kgm/
Explanation:
One ball moves to the right and the other moves opposite and momentum is a vector quantity so that considering the direction
Initial momenta are P₁=2x3=6kgm/s P₂=4x(-2)=-8kgm/s
Final momentum is the vector sum of P(final)= 6-8= -2 kgm/s

Given that,
A remote car makes 2 revolutions in 20 seconds.
We need to find the period of the object.
It means, it will make [tex]\dfrac{2}{20}=0.1\ \text{revolutions/second}[/tex] .
lt T be the period of the object. So,

The energy of the nuclear plant, [tex]E=10^{27}\ J[/tex]
We need to find how much mass wast lost.
The relation between energy and mass is given by :
[tex]E=mc^2[/tex]
