An example would be 2 types of motion. It could be rectilinear or projectile motion. There are various equations for each type. Since you don't want me to tell you the answer, I could just express it in words. Then, it will be up to you to translate into mathematical equations.
For rectilinear motion, the distance traveled is equal to the initial velocity times the time, plus one-half of the acceleration times the square of the time. For projectile motion, the maximum distance is equal to the square of the initial velocity multiplied with the square of the sine of the launch angle, all over twice the gravity.
Answer:
unknow e and f
Explanation:
In experiments with alpha particles that are obtained by the method of radioactive decay of atoms, some parameters are known
a) Known. The initial velocity is given by the energy of the particles entities by the atomic nuclei
b) Known. The particle charge always 2e, helium core
c) Known. It is set in the given experiment, in general it is selected as zero
d) Known. Placed by the experimenter
e) Unknown. The speed depends on the interactions with the system
f) Unknown. It depends on the interactions with the system, because the position depends on the interactions
g) Known. It is always the value of a helium nucleo
Answer:
b. Prone on 45 degree wedge positioned on the floor.
Explanation:
According to the pediatric therapists the most effective position to place the child in to facilitate anti gravity movement and promote hand usage is to prone on 45 degree wedge positioned on the floor.
Answer:
Part a)
Part B)
Explanation:
Part A)
At the top of the hump the force on the rider is
1) Normal force
2) weight
so here we know that
Part B)
At the top of the loop we will have
in order to remain in contact the normal force must be just greater than zero
so we will have
