Answer : The correct option is, Number
Explanation :
The periodic table is a type of table in which the element are systematically arranged on the basis of the atomic number.
The periodic table have the groups and periods. In the periodic table, there are 7 horizontal rows of elements are known as period and 18 vertical columns of elements are known as group.
Hence, 1A, 3B, and 7A are examples of group number on the periodic table.
We know that in a collision the momentum is conserved, that is:
Since this is vector equation we can divide it in two scalar equations, one for x and for y. Then we have:
Then we have for the x direction:
and for the y direction:
Hence, we have the system of equations:
From the second equation we have:
Plugging this in the first equation:
Now that we know the value of the angle we plug it in the expression for the velocity, then we have:
Therefore, the magnitude of the final speed of the orange ball is 1.04 m/s and the direction is 69.69°
Answer:
W/16
Explanation:
The force of gravity, W = mg = GMm/R²
When R increases by a factor of four, W decreases by 4² or 16.

Answer:
41 turns
Explanation:
= Induced emf = 12.4 mV
= Current changing rate = 0.0275 A/s
L= Inductance
= Average flux = 0.00285 wb
N = Number of turns
Change in flux is given by
Flux through each turn is given by
The number of turns is 41
