Answer:
A) It requires extremely high pressure.
Explanation:
The reasons why we haven't been able to harness power from fusion is that its energy requirements are unbelievably, terribly high.
Answer:
it does not mirror the image
Answer:
22) 5.6 Kg.m/s
23) 0.067 Kg
24) 1.16 m/s
Explanation:
Momentum is found by multiplying mass and velocity
P=mv where P is momentum, m is mass of object and v is the velocity
22
Given
Mass, m=2 Kg
Rate, v=2.8 m/s
Relationship
P=mv
Solution
P=mv=2*2.8=5.6 Kg.m/s
23
Given
Momentum, p=0.1 Kg.m/s
Rate, v=1.5 m/s
Relationship
P=mv and making m the subject then
Solution
24
Given
Momentum, 
Mass, 
Relationship
P=mv and making v the subject then
Solution
Answer:
The magnetic field will help to create an electromagnetic radiation which will prevent the charged particle from moving in a constant direction in a straight path.
Explanation: A magnetic field is an area around a particle where magnetic energy is felt or experienced, this ensures that all the charged particle within the magnetic field will be influenced by magnet.
In the highlighted situation, the magnetic field will help to ensure that an electromagnetic radiation is created to synchrotron radiation occurs effectively.
Answer:
4 m/s
Explanation:
From the law of conservation of momentum,
Total momentum before collision = Total momentum after collision
mu+m'u' = V(m+m')...................... Equation 1
Where m = mass of the arrow, u = initial velocity of the arrow, m' = mass of the apple, u' = initial velocity of the apple, V = Final velocity of the apple and the arrow after collision.
make V the subject of the equation
V = (mu+m'u')/(m+m').................... Equation 2
Given: m = 0.5 kg, m' = 2 kg, u = 20 m/s, u' = 0 m/s(initially at rest)
Substitute into equation 2
V = (0.5×20+2×0)/(2+0.5)
V = 10/2.5
V = 4 m/s.
Hence the final velocity of the apple and the arrow after the collision = 4 m/s
