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.
Answer:
The magnetic field is 
Explanation:
From the question we are told that
The mass of the metal is 
The current is 
The distance between the rail(length of the rod ) is 
The coefficient of kinetic friction is 
Generally the magnetic force is mathematically represented as

Given that the rod is moving at a constant velocity, it
=> 
Where
is the kinetic frictional force which is mathematically represented as

So

=> 
substituting values
=> 
=> 
Im not conpletely sure but 6pt or about 2.7-2.8 L of water
A lunar eclipse occurs when the Moon passes directly behind Earth and into its shadow. This can occur only when the Sun, Earth, and the Moon are aligned (in syzygy) exactly or very closely so, with the planet in between. Hence, a lunar eclipse can occur only on the night of a full moon. The type and length of an eclipse depend on the Moon's proximity to either node of its orbit.
During a total lunar eclipse, Earth completely blocks direct sunlight from reaching the Moon. The only light reflected from the lunar surface has been refracted by Earth's atmosphere. This light appears reddish for the same reason that a sunset or sunrise does: the Rayleigh scattering of bluer light. Due to this reddish color, a totally eclipsed Moon is sometimes called a blood moon.
