Answer:

Long time after CLOSING the KEY the potential difference across the CAPACITOR BECOMES zero

Explanation:

Let q charge flows out from capacitor 1 and 2 and enters into capacitor 3

so we will have kirchoff's loop law

So final charge on each capacitor will be

now potential across each capacitor is given as

Yes it is possible to have a negative value in displacement but not in speed.

Negative displacement means displacement in OPPOSITE DIRECTION.

(Because displacement is a vector quantity)

But speed is always positive because it is a SCALAR quantity and only has magnitude.

PLZ MARK ME BRAINLIEST!!*!*!

Two VECTORS a and b have equal magnitudes of 12 units. These vectors are making ANGLES 30° and 120° with the x axis respectively. Their SUM is r. Find the x and y components of r.

magnitude of vector a = magnitude of vector b = 12 units.

vector a makes an angle 30° with x-axis.

so, a = 12(cos30° i + sin30° j)

= 12(√3/2 i + 1/2 j)

= 6√3 i + 6 j

again, vector b makes an angle 120° with x - axis .

so, b = 12(cos120° i + sin120°j)

= 12(-1/2 i + √3/2 j)

= -6 i + 6√3 j

a/c to question, r = a + b

so, r = (6√3 i + 6j) + (-6I + 6√3j)

= (6√3 - 6)i + (6 + 6√3)j

so, component of vector r along x-axis = (6√3 - 6)

so, component of vector r along x-axis = (6√3 - 6)and component of vector r along y-axis = (6 + √3)

For a photon E=h.f (f=frequency) = hc/l (c=velocity of light)

Hence E = p.c for photons.

For non RELATIVISTIC bodies p = m.v and E = (1/2) m.v^2 so E = (p^2)/2m. This assumes m = REST MASS is independent of velocity. In general this is not TRUE if v^2/c^2 is not ~0 since m=m0/sqrt(1-v^2/c^2). So this formula is only valid at velocities at which relativistic EFFECTS can be ignored.

B is the CORRECT ANSWER of this QUESTION

Answer:

Newton's law of UNIVERSAL gravitation is usually stated as that every particle attracts every other particle in the universe with a force that is directly proportional to the product of their masses and INVERSELY proportional to the SQUARE of the distance between their centers.

EFFICIENCY signifies a peak level of performance that uses the least amount of inputs to achieve the highest amount of output. Efficiency requires reducing the NUMBER of unnecessary RESOURCES USED to produce a given output including personal TIME and energy

Answer:

EXPLANATION:

Five bulbs consume the power of 100 W each.

The TOTAL power consumed by 5 bulbs = 5 x 100 = 500 W = 0.5 kilowatt

Electrical energy consumed daily is, E = P x t = 0.5 kW x 10 hours = 5 kWh.

THUS, total electrical energy consumed for 30 days = 5 kWh x 30 days = 150 kWh or 150 units.

The cost of 1 unit of ELECTRICITY = Rs. 4

Thus, the total cost of electricity = Rs. 4 x 150 = Rs. 600

Formulas used :-

› v² - u² = 2gh

› =

› TAN θ =

SOLUTION :-

• Velocity of the particle thrown vertically upwards, = - 2g ()

• = - sin²α

• =

• = cos α

• Velocity of the particle in a projectile MOTION, = cos α

As, after collision they meet at a specific POINT (SEE attachment), let's make the components.

Now, let's divide the velocities in order to find the slope.

• tan θ = 1 = 45°

• tan θ =

Answer:

The third LAW of motion states that if a body exerts a force on a second body, the second body exerts a force that is equal in magnitude and OPPOSITE in DIRECTION to the first force. So for every action force there is always a REACTION force.

ANSWER:

An acceleration can cause SPEED to INCREASE, decrease, and EVEN stay the same! Acceleration tells you the rate at which the VELOCITY is changing. ... The acceleration can change the magnitude and/or the direction of the velocity. Speed is only the magnitude of the velocity.

Answer:

what is elastic collision

An elastic collision is an encounter between two BODIES in which the total KINETIC energy of the two bodies REMAINS the same. BASICALLY, in the CASE of collision, the kinetic energy before the collision and after the collision remains the same and is not converted to any other form of energy.
