Answer:
Explanation:
Distance between ship and enemy ship
= 500 + 610
= 3110 m
Range of projectile
R = u² sin2θ / g
= (250x 250 sin 150) / 9.8
= 3188m
The projectile falls within a distance of 3188 - 3110 = 78 m from enemy ship
Height of mountain = 1800 m
We shall find the height of projectile when its horizontal displacement is 2500m
x = 2500 , y = ?
u = 2500 ,
y = x / cos θ - .5 g x² /u²cos² θ

9660 - 7315 m
= 2345 m
It is within 545 m from mountain peak .
Answer:

Explanation:
We are given that
Distance between plates=d=2.2 cm=


Using 
We have to find the magnitude of E in the region between the plates.
We know that the electric field for parallel plates





Where 
Substitute the values


Hence, the magnitude of E in the region between the plates=
Answer:
It would be static discharge and conduction
Explanation:
The conduction of static energy is pulled throughout the clothes and left over static electricity is what causes the spark.
<span>Amplitude is the maximum extent of vibration
As by increasing the amplitude the wave speed ,frequency and wavelength will remain same so it will increase </span><span>the speed of the individual particle in the medium.
This will increase wave energy
so correct option is B
hope it helps</span>
