Explanation:
1. The structures should be made with good quality steel and concrete so that they can bear load and deformation.
2. Buildings should be made laterally strong so that they can overcome dominant lateral forces.
3. In High seismic activity areas devices such as energy absorbers should be used. Base isolation must necessarily be done.
4. Use of hybrid Fiber Reinforced Concrete to increase the toughness of a structure in a Moment Resisting Frame. Moment resisting frames are frames that resist moment of any devices.
I think we will use the law of conservation of linear momentum;
M1V1 = M2V2
M1 = 4 kg (mass of the water balloon launcher)
V1=?
M2= 0.5 kg ( mass of the balloon)
V2 = 3 m/s
Therefore; 4 V1 = 0.5 × 3
4V1= 1.5
V1= 1.5/4
= 0.375 m/s
Because the light from it travels to you about 874 thousand times
as fast as the sound does, so the hearing part falls behind the seeing
part.
Answer:
The magnitude of electron acceleration is

Explanation:
Given:
Distance from the wire to the field point
m
Speed of electron 
Current
A
For finding the acceleration,
First find the magnetic field due to wire,

Where 

T
The magnetic force exerted on the electron passing through straight wire,

N
From the newton's second law

Where
mass of electron
kg
So acceleration is given by,



Therefore, the magnitude of electron acceleration is
