The sun creates nuclear energy in it's core and as a byproduct heat is created. It gives this off in the form of heat and radiation.
Answer:
The 24th term is 80 and the sum of 24 terms is 1092.
Explanation:
Given that,
The arithmetic series is
11,14,17,........24
First term a = 11
Difference d = 14-11=3
We need to calculate the 24th term of the arithmetic sequence
Using formula of number of terms
Put the value into the formula
We need to calculate the sum of the first 24 terms of the series
Using formula of sum,
Put the value into the formula
Hence, The 24th term is 80 and the sum of 24 terms is 1092.
Ok so basically you have to look at the work and then look at the work and then it will show
Answer:
Momentum change of the rock = 3835 kgm/s
Chane in earth's velocity = 6.4 x 10⁻²² m/s
Explanation:
m = 50.0 kg, M = 6.0 x 10²⁴ kg
d = 300.0 m
final velocity of rock = v, v² = 2gd = 2 * 9.81 * 300, so v = 76.7 m/s
Momentum change of the rock = mv = 50.0 * 76.7 = 3835 kgm/s
Inital momentum of the rock+earth system = 0
final momentum = 0 (momentum conservation)
momentum of rock and momentum of earth are same magnitude and opposite directions.
mv - MV = 0
Chane in earth's velocity = mv/M = 3835/(6.0 x 10²⁴) = 6.4 x 10⁻²² m/s
Answer:
0.695 m
Explanation:
α = angular acceleration of the fan blade = 14.1 rad/s²
a = tangential acceleration at the point concerned = acceleration due to gravity = 9.8 m/s²
r = distance of the point from axis of rotation at which tangential acceleration is same as acceleration due to gravity
We know the relation between
a = r α
Inserting the values
9.8 = 14.1 r
r = 0.695 m
