Answer: 2 x 5.5= 11 m
Explanation: distance is equal to speed multiplied by time
Knowing that when you throw something in the air, the speed will be 0m/s.
The acceleration due to gravity is 9.8m/s^2.
v2=0
v1=24
a=9.8
The formula is:
v2=v1+a(t)
v2-v1/a=t
0-24/9.8
24m/s/9.8m/s^2=t (You can choose which direction is positive and negative)
2.45s=t
t=2.45*2s (Since you calculate both going up and down)
t=4.9s
Answer:
1.44*10^-3m
Explanation:
Given that distance BTW two bright fringes is
DetaY = lambda* L/d
So for second wavelength
Deta Y2= Lambda 2* L/d
=lambda 2 x deta y1/ lambda1
So substituting
= 360 x 10^-9 x (1.6*10^-3/640*10^-9)
1.44*10^ -3m
HeLLo tHeRe!
Your answer should be public transportation vouchers
Hope this helps. Have a nice day.
