Answer:
Electric field in the membrane is given as
Explanation:
As we know that electric field in a region is related to its potential difference given by the formula
here we know that
so we have
The term Point Charge describes a model in which a charge takes up no space and acts uniformly on its surroundings. A Point Charge also creates lines that are uniform in nature and can go both outwards or inwards. When it goes outwards, it shows a positive charge and when it goes inwards then it shows a negative charge.
Answer
given,
mass of block = 2.7 kg
speed of block = 1.1 m/s
a) spring compressed to distance of 6 cm or 0.06 m
using conservation of energy
kinetic energy is converted into spring energy
k= 907.5 N/m
b) again using conservation of energy
kinetic energy is converted into spring energy
v= 0.275 m/s
Answer:
Explanation:
A ) weight of air + weight of tank = 013.5 + 3.2
= 16.7 kg
volume of air
= 3.2 / 1.225 = 2.61 m³
= volume of water displaced = 2.61 m³
weight of water displaced = 2.61 x 1025
= 2675.25 kg
buoyant force = 2675.25 kg
buoyant force = weight of displaced sea water
= volume of displaced sea water x density
= 15.7 x 10⁻³ x 1025
= 16.0925 kg
net force = buoyant force - weight
= 2675.25 - 16.7
= 2658.55 kg
B ) net force will be in downward direction as weight is higher .
C ) weight of tank + weight of water in it
= 13.5 + 15.7 x 10⁻³ x 1025
= 13.5 + 16.0925
= 29.5925 kg
buoyant force = 16.0925 kg
net force = 29.5925 - 16.0925
= 13.5 kg
D ) net force down wards
