The chemical bonds alow it to pass to the other object.
Dark matter has been detected by its gravitational pull.
Initial state the pressure and volume are
P = 1 bar
V = 1 litre
Now the process equation is given as
PV = constant
So now the pressure is increased to
P = 4 bar
so volume must decrease by 4 times
so final volume is
V = 0.25 litre
Now the pressure is constant and volume again increased to V = 1 litre
Now in final step the volume will become constant and again pressure will become P = 1 bar
so this is a cyclic process and figure is attached at following
Answer:
Explanation:
Q₂ is at the origin and Q₁ is at 12 cm on x -axis
Force between Q₁ and Q₂
= K x Q₁ x Q₂ / .12 where k is a constant equal to 9x 10⁹
Force F = 9 x 10⁹ x Q₁ x Q₂ / .12²
= 625 x 10⁹ x Q₁Q₂ N
This is the force each one exerts on other . So electric force on Q₂ due to Q₁ is 625 x 10⁹ x Q₁Q₂ N . Its direction is towards left as both will repel each other.
b)
Electric field due to charge Q₂ at - 2 cm
= 9 x 10⁹ x Q₂ / .02²
= 22500 x 10⁹ x Q₂ N/C , towards left .
Electric field due to charge Q₁ at - 2 cm
= 9 x 10⁹ x Q₁ / .14²
= 459.18 x 10⁹ x Q₁ N/C , towards left
As both the fields are to the same direction
Net field = 75 x 10⁹ x Q₂ + 459.18 x 10⁹ x Q₁
10⁹ ( 22500 x Q₂ + 459.18 x Q₁ ) N/C .
Direction will be towards left.
Explanation:
Given that,
Mass of an elevator, m = 800 kg
It is lifted vertically by a strong rope
The equation of motion, when the elevator is lifted vertically up is :
T-mg = ma
a is the acceleration of the elevator
We need to find the acceleration of the elevator if the rope tension is :
(a) 9000 N
Put T = 9000 N,
T-mg = ma

(b) 7840 N
Put T = 7840 N,
T-mg = ma

(c) 2000 N
Put T = 2000 N,
T-mg = ma

Hence, this is the required solution.
