Solution :
Mass is varied keeping frequency constant.
Wavelength, λ 
where length of spring = l
number of segments = n
Velocity, v = λ x f
= 
= mass density, T = tension in string
, n = 2
Therefore, μ = 0.002785 kg/ m
Frequency is varied keeping T constant
f = 210 Hz
Answer:
For Pentium 4 Prescott:
% of Static Power = 10
For core i5 Ivy Bridge:
% of Static Power = 43
Given Information:
Static Power of P4 = 10 W
Dynamic Power of P4 = 90 W
Static Power of i5 = 30 W
Dynamic Power of i5 = 40 W
Required Information:
% of static power w.r.t total power dissipation = ?
Explanation:
For Pentium 4 Prescott:
% of static power = static power/total power * 100
% of static power = 10/(10 + 90) * 100
% of static power = 10/(100) * 100
% of static power = 10
For core i5 Ivy Bridge:
% of static power = static power/total power * 100
% of static power = 30/(30 + 40) * 100
% of static power = 30/(70) * 100
% of static power = 43 (rounded to nearest whole integer)
Answer:
1. because of the tilted axis of earth the seasons in northern hemisphere are the exact opposite of the southern. because the sunrays reaches the earth an different points and when the earth moves around the sun it changes the hemisphere which is tilted to the sun.
2. the northern hemisphere is in Winter and the southern in summer. because the southern is tilted to the sun and the northern not so less sunrays reaches the northern hemisphere.
I'm sorry my explanation are bad
B. instantaneous speed
The speedometer of a car show instantaneous speed.
Instantaneous speed is the motion rate of a car (in this example) at a particular moment or instant in time. It can be calculated by dividing a portion or a part of the total distance (of the trip) by time traveled.
