Answer:

Option B

Explanation:

Given

The current flowing through the circuit = 1 Ampere

As we know

I is inversely proportional to resistance.

I α 1/r

or I = k/r

If the resistor "r" is replaced by any resistor "R" with resistance = 2r, then the current will be

I = 1/2 of 1 ampere

I = 0.5 Ampere

Hence, option B is correct

nikklg [1K]
Given:
F = 39 N, the force applied
t = 2 s, the time interval in which the force is applied.

By definition, the impulse is
I = \int_{0}^{2} F(t) dt = \int _{0}^{2} 39dt = 39*2=78 \, N-s

Answer: 78 N-s

krek1111 [17]

Answer:

Polar bears (Ursus maritimus) are of special interest because of their large size, white color and position as the top-level carnivore in the remote arctic environment. They occur only in the northern hemisphere nearly always in association with sea ice. They have only two colors of fur: tan and white. Polar bears were created to withstand cold temperatures and are quite adaptable. Polar bears are ferocious and the most dangerous of bears. They can lop a person's head off with one swoop of their paw.
