Answer:
acceleration = 22.14 m/s²
time = 2.80 s
Explanation:
given data
initial velocity = 31.0
final velocity =
time = 1.40
solution
we get here acceleration that is
acceleration =
...............1
acceleration =
acceleration = 22.14 m/s²
and
by kinematic equation of motion
v = u +at .........2
t =
time = 2.80 s
Answer:hat are some examples of energy transformation?
The Sun transforms nuclear energy into heat and light energy.
Our bodies convert chemical energy in our food into mechanical energy for us to move.
An electric fan transforms electrical energy into kinetic energy.
Explanation:
Formula:
F = ma
F: force (N) m: mass (kg) a: acceleration (m/s^2)
Solution:
F = ma
F = 1200 × 1.89
= 2268N
C = 3 uf = 3 × 10^(-6) f
v = 6volts
Q = C.v
= <span>3 × 10^(-6) </span>× 6
= 18 × 10^(-6)
= 1.8 = 10^(-5)
