If a gun is sighted to hit targets that are at the same height as the gun and 85 m away at the same height, how low, as a positive number in meters, will the bullet hit if aimed directly at a target 180 m away
The muzzle velocity of the bullet is 275 m/s
Answer:
y = -1.1109 m
Explanation:
Range =
range = 85 m
velocity = 275 m/s
g = 9.8 m/s²
If the bullet is aimed at a target 180 m, time required to travel 180 m with horizontal component will be;
t = 0.6546 sec
To determine, how low as a positive number in meters.
y =
y = 0.9909 - 2.1018
y = -1.1109 m
54-(15x2) divided by 2 = 12
54 - 15 = 39
39-15=24
24 divided by 2=12
Length:15
Width:12
Perimeter:54
The line in which waves that are moving together are all in the same phase is referred to as the wave front.
For example, in a series of waves, all of the crests that are in a single line make up a single wave front. This is the case for every set of particles at the same specific point in a series of waves.
Answer:
Option B
Explanation:
Kinetic Energy is the energy possessed by the body due to <u>"motion"</u>.
Answer:
The charge on point A is = 2.4 × C
The charge on point B is = 1.2 × C
Explanation:
Given data
Distance (r) = 0.19 m
Magnitude of the charge on A is twice that of the charge on B i.e.
F = 46 N
We know that force between the charges is given by
= 1.2 × C
= 2 ×
= 2 × 1.2 ×
= 2.4 × C
Therefore the charge on point A is = 2.4 × C
The charge on point B is = 1.2 × C
