Verdich [7]3 years ago
7 0

Answer:

Diffusion is the movement of a molecule from an area where the molecule is in high concentration to an area where the molecule is in low concentration. Facilitated diffusion is the movement of a molecule from an area of high concentration to an area where the molecule is in low concentration. Osmosis is the diffusion (high to low concentration) of water through a semi-permeable membrane. Water moves from an area of high water molecule concentration (and lower solute concentration) to an area of low concentration (and higher solute concentration.

Hope this Helps!!!

What current is taken by the lamp when it is connected to a 220 v mains supply? what is the resistance of the lamp
eimsori [14]

Answer:

Given parameters

Potential difference (V) = 220 V

Power of lamp 1 (P1) = 100 W

Power of lamp 2 (P2) = 60 W

Both the bulbs are connected in parallel. Therefore, the potential difference across each of them will be 220 V, because no division of voltage occurs in a parallel circuit.

We know that

Power = Voltage x Current

P = V x I

I = P/V

Lamp 1:

I1 = P1/V

I1 = 100/220

I1 = 5/11 A

Lamp 2:

I2 = P2/V

I2 = 60/220

I2 = 3/11 A

Net current (I) = I1 + I2

I = 5/11 + 3/11

I = 8/11

I = 0.7273 A

Hence, current drawn from the line is 0.727 A

Which of the following accurately describe some aspect of gravitational waves? Select all that apply. (A) Gravitational waves co
crimeas [40]

Explanation :

The points regarding the gravitational waves are as follows :

(1) Gravitational waves are predicted to travel through space at the speed of light. So, the speed of gravitational waves is also equals c=3\times 10^8\ m/s.

(2) The first direct detection of gravitational waves came in 2015. It is detected using a advanced LIGO detectors.

(3) The existence of gravitational waves is predicted by Einstein's general theory of relativity.

Hence, the correct options are (B), (D) and (E).

A person riding on a bus hears the horn of a car that the bus is approaching. After the bus passes the car and is traveling away
Grace [21]

Answer:

option (c)

Explanation:

According to the doppler's effect, the frequency of sound decreases.

If there is a relative motion between the source and the observer, the frequency of sound changes apparently.

the formula of the doppler effect is given by

f' =\frac{v-v_{o}}{v}}f

where, f is the real frequency, v be the speed of sound, vo be the speed of the observer, here, the bus is the observer.

So, the value of f' < f
