Answer:
2
Explanation:
Divergent boundaries are areas where plates move away from each other, forming either mid-oceanic ridges or rift valleys. These are also known as constructive boundaries. ... Subduction zones occur where an oceanic plate meets a continental plate and is pushed underneath it. Subduction zones are marked by oceanic trenches.
<span> Ok, so slope of the lane gives the ball a constant acceleration of 1.8 m/s for 2.5 s
[lane slope = arcsine (1.8/9.8) = 10.6°]
which increases speed of the ball by
1.8(2.5) = 4.5 m/s
The ball reaches the pins with a speed = 7.6 m/s, so it must have left Josh's hand with a speed of
7.6 - 4.5 = 3.1 m/s ANS</span>
Answer:
<h2>50
°</h2>
Explanation:
Angle of rotation of the flat polished surface = 15°
angle of incidence i = 20°
Since the polished surface is turned at an angle of 15°, the angle of reflection
r = 2 (Note that the angle of rotation only have effect of the angle of reflection)
r = 2*15 = 30°
The angle between the reflected ray and the incident ray will be equal to the sum of the angle of incidence and the angle of reflection i.e i+r
The angle between the reflected ray and the incident ray = 20°+ 30° = 50°
It doubles
Momentum= mass * velocity
when velocity doubles
momentum= 2*(velocity* mass)
Answer:
Explanation:
Induced EMF in the coil is given by the equation
so we have
also we know that rate of change in current in solenoid is given as
so induced EMF of coil is given as
now induced current in the coil will be given as
