Two statements, that describe what happens in both nuclear fusion and nuclear fission reactions, are:
Radiation is released from the nuclei that undergo a reaction.A small amount of the mass in each nucleus that undergoes a reaction is converted to energy.Hence, option (C) and (D) are correct.
What is nuclear reaction?A nuclear reaction is a process in nuclear physics and nuclear chemistry where two nuclei or a nucleus and an outside subatomic particle meet to create one or more new nuclides. Consequently, at least one nuclide must change throughout a nuclear reaction.
Instead of being referred to as a nuclear reaction, the process is simply referred to as a sort of nuclear scattering if a nucleus interacts with another nucleus or particle and they subsequently separate without altering the nature of any nuclide.

A proton moves perpendicularly to a magnetic field that has a magnitude of 4.20 x 10-2 T. What is the speed of the particle if the magnitude of the magnetic force on it is 2.40 x 10-14 N?
Answer:
V=3.57 × 10^6 m/s
hope it is helpful..
The speed of the proton in the magnetic field is 3.57×10⁶ m/s.
To determine the speed of the proton, we need to know about the magnetic force experienced by a charged particle in a magnetic field.
What is the magnetic force on a charge particle in a magnetic field?From lorentz law, the magnetic force on a charge particle is given asF=q×v×B
where, q= charge of the particle
v= speed of the particle
B= magnetic field
What will be the speed of the charge particle, proton, if the magnetic field and force are given?Magnetic force(F)= q×v×Bv=F/(q×B)
Here, B= 4.20×10⁻²TF=2.40×10⁻¹⁴N
q= 1.6×10⁻¹⁹C
Then, v= 2.40×10⁻¹⁴/ ( 4.20×10⁻²× 1.6×10⁻¹⁹)
= 3.57×10⁶ m/s.
Thus, we can conclude that the speed of the proton in the magnetic field is 3.57×10⁶ m/s.

what is acceleration
Answer: acceleration means the speed is changing, but not always. When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing.

The kinetic energy of a body moving at a speed of 10 m / s is equal to 1000 J. What is the body mass
Answer:
m = 20 kg
Explanation:
Given that,
The speed of a body, v = 10 m/s
Kinetic energy of the body, K = 1000 J
We need to find the mass of the body. The formula for the kinetic energy of a body is given by :
[tex]K=\dfrac{1}{2}mv^2\\\\m=\dfrac{2K}{v^2}\\\\m=\dfrac{2\times 1000}{(10)^2}\\\\m=20\ kg[/tex]
So, the mass of the body is equal to 20 kg.

Are acceleration and force proportional or inversely proportional values?
Answer:
Yes, acceleration and force are directly proportional to each other.
Explanation:
The force acting on an object is given by :
F = ma
Where
m is mass
a is acceleration
It can be clear from the above formula that the acceleration and the force are directly proportional to each other.

Answer:
5
Explanation:
From the attachement,
M.A = Load(L)/Effort(E)
M.A = L/E...................... Equation 1
Where M.A = .Mechanical Advantage, L = Load, E = Effort.
Given: L = 500 N, E = 100 N
Substitute these values into equation 1
M.A = 500/100
M.A = 5.
Hence the actual mechanical advantage of the pulley is 5

Two kids are roller skating. Amy, with a mass of 55 kg, is traveling forward at 3 m/s. Jenny, who has a mass of 40 kg, is traveling in the opposite direction at 5 m/s. They crash into each other and hold onto each other so that they move as one mass. How fast are they traveling? How would you find your answer?
Answer:
They traveling at along the direction of 55 kg kid.
Step-by-step explanation:
Conservation of momentum-
Momentum of a system is constant if there are no external forces acting on the system.
As they crash into each other and hold onto each other so that they move as one mass and no other force is acting on them, so conservation of momentum can be applied here.
The final direction of velocity will be opposite to the assumed direction of the mass of 40 kg.
This is a conservation of momentum problem. The equation relevant here is
[tex]\[m_1v_1+m_2v_2=\left ( m_1+m_2 \right )v_f\][/tex]
where m is the mass and v is the velocity. Because Amy and Jenny move as one mass after crashing (or colliding) with each other, this is an inelastic collision. What we to find is the final velocity, [tex]v_f[/tex], of both Amy and Jenny as a single body.
[tex]v_f=\frac{m_1v_1+m_2v_2}{\left ( m_1+m_2 \right )} = \frac{(55)(3)+(40)(5)}{(55+40)} = \text{3.84 m/s}.[/tex]

What would it mean if an object had no potential energy?
As a cold air mass advances on a warm air mass, what usually comes before it?
Answer: A cold front occurs when a cold air mass advances into a region occupied by a warm air mass. If the boundary between the cold and warm air masses doesn't move, it is called a stationary front.
Explanation: Two types of occluded front exist: the warm-type and the cold-type. They’re distinguished by the relative temperatures of the air mass ahead of the occlusion – in other words, the air mass ahead of the original warm front – and the air mass behind the cold front. If the air behind the cold front is colder than the air ahead of the occlusion, it shoves beneath that air (because it’s denser) to form a cold-type occluded front. If the air behind the cold front is warmer than the air ahead, it rides over it to form a warm-type occluded front – which appears to be the more common case. In either situation, the lighter warm air representing the air mass originally between the warm and cold fronts sits above the boundary between the two cooler air masses.

How far does a sound wave travel in 3 seconds if the air temperature is 30 degrees
Celsius?
a) 114.33 m
b) 1047 m
c) 1029 m
d) 116.33 m
Answer:
B
Explanation:
v=349m/s
d=vt
d=349*3
d=1047m
WHY 349??
Because, velocity of sound increases about 0.6 m/s for every 1 degree celsius rise in temp.
Velocity of sound is about 343 m/s at 20 degrees C, so 0.6*10=6 more m/s, or 349 m/s. Kinda cool how temperature alters the speed of sound!
Which can make 4 covalent bonds? Carbon, Silicon, or both?
Answer:
I would say both
Explanation:
Each silicon atom has four valence electrons which are shared, forming covalent bonds with the four surrounding Si atoms.
Carbon contains four electrons in its outer shell. Therefore, it can form four covalent bonds with other atoms or molecules. The simplest organic carbon molecule is methane (CH4), in which four hydrogen atoms bind to a carbon atom (Figure 1).
Do all force interactions cause a noticeable change in motion? Explain your thinking?
!THANK YOU!
Answer:
No. If you apply a force in a chair, for example, you only will be able to move the chair if you beat the static frictional force. So, with that example, we can see that is not any type of force that can produce movement. The only force that produces movement is a result force which is non-zero.
