The answer would be A, as B refers to conduction and C and D refer to radiation. Convection is the transfer of different temperature currents, i.e, A
Answer:
a. 10.0 J
Explanation:
Given parameters:
Weight of bowling ball = 10N
Height of building = 5m
Distance of fall = 1m
Unknown:
Kinetic energy of the ball = ?
Solution:
Kinetic energy is the energy due to the motion of a body.
Mathematically;
K.E = mv²
Since this body is falling under gravity;
K.E = mgh
mg = weight of the ball
h is the height
Insert the parameters and solve;
K.E = 10 x 1
K.E = 10J
Answer:
D
Explanation:
calculate effective resistance of the resistors
= 80 + 120
= 200
overall resistance = 48 ohms
so overall current flowing through circuit
I = V / R
I = 12 / 200
I = 0.06 A
since circuit is in series, current is same at every point so...
potential difference across 80 = R x I
= 80 x 0.06
answer is potential difference = 4.8 V
