Answer: Highest point from the ground that ball reaches = 5.102
Explanation:
Formula -
v² - u² = 2as
final velocity v = 0
initial velocity u = 10m/s
acceleration a = g (gravity)=9.8
distance s = 3m+x (x is the height after 3m that object reaches)
0-(10)² = 2 (-g)*(3+x)
-100 = -2g*(3=x)
(3+x)=100/2g
3+x = 100/2*9.8 = 100/19.6 = 5.102
x=5.102-3
x=2.102
So, the highest point will be
3+x = 3+2.102
=5.102m
Albedo than land or higher
Answer:
The same in both the regions of constructive interference and the regions of destructive interference.
Explanation:
Interference is a phenomenon which occurs when two waves meet while moving along the same medium . The amplitude formed as a result of the interference could be greater, lower, or the same amplitude.
Constructive and destructive interference result from the interaction of waves that are correlated or coherent with each other. This is because arose from the same source or they have the same or nearly the same frequency.
The waves being coherent, arising from the same source and having the same frequency explains why it’s the same in both the regions of constructive interference and the regions of destructive interference.
Answer:
- 1 m/s ( here (-) means the opposite direction of A)
Explanation:
Let m1=2kg, m2=2kg,u1= 3m/s,u2= -2 m/s, v1= 1m/s
m1u1+m2u2= m1v1+m2v2
2×3+2×(-2) = 2×1 + 2x
2= 2(1+x)
x = -1
