Answer:
The acceleration is 8 m/s²
Explanation:
The given parameters are;
The initial velocity, u = 2 m/s
The final velocity, v = 6 m/s
The distance the acceleration took place, s = 2 m
The acceleration, a, can be found from the following kinematic equation;
v² = u² + 2·a·s
By substituting the values, we have;
6² = 2² + 2 × a × 2
6² - 2² = 2 × a × 2
32 = 4·a
a = 32/4 = 8 m/s²
The acceleration, a, of the given motion = 8 m/s².
Answer: 18 blocks in total ( 17 add to the original in contact with the ground)
Explanation:
The pressure on the face in contact with the ground ( we choose the face 0.15m x 0.082m)
Pressure= Force ( weigth) /Area
1 Atm = 101325 Pascal [N/ m^2]
Answer:
A
Explanation:
Ans- A, causes sediments in aquifers that are emptied to compact and the ground above it to sink.
This is one of the major problems for California nowadays. Due to excessive groundwater pumping to satisfy the demand of huge population the aquifers are drying, hence compacting and for that the land above sinks.
Answer:197.504 N
Explanation:
Given
Two Charges with magnitude Q experience a force of 12.344 N
at distance r
and we know Electrostatic force is given



Now the magnitude of charge is 2Q and is at a distance of 

F'=16F
F'=197.504 N
