Vector explanation is apex and I got 100 on the test and it’s the definition
Answer:
2.8 m/s
Explanation:
Energy of a system cannot be destroyed . It can only be transfer to another form of energy.
when the pendulum is at rest in a height 0.4 m , it has a potential energy due to the height it is. but no kinetic energy since ni movement (velocity)
at the time it reach the lowest point of the path , we can say that it is in the minimum potential level , therefore it now does not have any potential energy , but has a kinetic energy
energy at rest = energy at lowest point
KE1 + PE1 = KE2 + PE2
0 + 1.5 * 9.8 *0.4=
V=√(2*9.8*0.4)
V = 2.8 m/s
Im not sure if this is physics or mathematics. but if 300 msec then per minute this will equal to 300 X 60 sec =18000 m per minute
Answer:
When two or more forces are acting on a body, then the total of all the forces which causes the resulting effect is the resultant force or net force. As force is a vector, we need to take the vector sum of all the forces to calculate the resultant.
Explanation:
Answer:
gamma waves
Explanation:
gamma rays" from lightning discharges at 10 to 20 MeV, and known to be produced by the bremsstrahlung mechanism. Another example is gamma-ray bursts, now known to be produced from processes too powerful to involve simple collections of atoms undergoing radioactive decay.
