<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2><h2>_____________________________________</h2><h3>DATA:</h3>
Height of Aeroplane = 500 meters
Speed of Aeroplane = 200 m/s
Acceleration due to gravity = g = 10m/s^2
time of package to reach the ground = t = ?
Horizontal distance = d = ?
<h2>_____________________________________</h2><h3>SOLUTION:</h3>When the bomb is dropped, it will have an initial horizontal velocity which is equal to the speed of the plane as the plane is just moving in horizontal direction. So the bomb fall and will travel forward.
Initial horizontal velocity is given by,
Initial vertical velocity is given by,
By the second equation of motion under gravity,
<u>For horizontal distance(d)</u>:
Horizontal distance has no acceleration thus d is given by
d = vt
d = 200x10
d = 2000 meters

Answer:
2.4 mm
Explanation:
Given that:
Initial Original length of the wire L = 3 mm
The stretch of the first wire ΔL= 1. 2 mm
The length of the second wire L'' = 6 mm
The stretch of the second wire ΔL'' = ???
Considering the Tension of the system; the Young modulus and the cross sectional remains constant ; as such:
Thus, the same material under the same tension stretches 2.4 mm
Answer:
Heat required to raise the temperature of the aluminium is 4750 J
Explanation:
As we know that the heat energy required to raise the temperature of the aluminium is given as
here we know that
m = 50 g
so we have
