Answer:
It reminds us that we need to work harder. It allows us to make adjustments in the way and manner in which we train and practice. In a loss, we are able to identify our vulnerabilities and weaknesses, and work to improve.
Explanation:
Answer:
D. It can be Cyclic
Explanation:
Science has all different kinds of alike processes.
The scientific method is a generally and usually a Cyclical Process.
Answer:
0.012 m
Explanation:
m = mass of the marble = 0.0265 kg
M = mass of the pendulum = 0.250 kg
v = initial velocity of the marble before collision = 5.05 m/s
V = final velocity of marble-pendulum combination after the collision = ?
using conservation of momentum
m v = (m + M) V
(0.0265) (5.05) = (0.0265 + 0.250) V
V = 0.484 m/s
h = height gained by the marble-pendulum combination
Using conservation of energy
Potential energy gained by the combination = Kinetic energy of the combination just after collision
(m + M) gh = (0.5) (m + M) V²
gh = (0.5) V²
(9.8) h = (0.5) (0.484)²
h = 0.012 m
I believe this is it
The centripetal force is given by
F = mv^2 / r
When v' = v/2,
F' = mv'^2/r = m(v/2)^2/r = mv^2/4r = F/4.
So the centripetal force is divided by 4.
Alpha radiation consists of fast-moving helium particles, and Beta radiation consists of electrons. Although helium particles are tiny, and electrons even tinier, these still consistent matter. Alpha and Beta waves consist of matter.
Gamma radiation consists of pure energy in the form of electromagnetic rays, and therefore do not consist of matter.
The answer is A) It does not consist of matter
