Answer:
speed are different at different places
Explanation:
because it's top speed is 50km/h,so it's initial speed may be less. when it covers some distance it's speed changes again. then we have given a mean speed .mean speed means sum of all speed divided by sum of total time.so the mean speed and final speed differs from each other
Answer:
its 0
Explanation:
because there is only 4999 right so its 0
Answer:
38.33°C
Explanation:
Applying,
180/100 = (F-32)/C............. Equation 1
Where F = Temperature of the hot day in fehrenheit, C = Temperature of the hot day in centigrade.
make C the subject of the equation
C = 100(F-32)/180.............. Equation 2
From the question,
Given: F = 101°F
Substitute into equation 2
C = 100(101-32)/180
C = 38.33°C
Answer:
Wave 1 and Wave 2.
Explanation:
We know that the general equation of a wave is given by :
or
We know that the speed of a wave is given by :
Where
= angular speed
k = propagation constant
Wave 1.
Wave 2.
Wave 3.
Wave 4.
It is clear that wave 1 and 2 have the same speed i.e. 7 m/s. Hence, this is the required solution.
