Answer:
from collisions between other galaxies
Explanation:
There are four types of galaxies based on their shape
The irregular galaxies are named so since they do not fit any of the above three shapes
They are formed by the collision between two galaxies. The battle between the gravitational forces of the nucleus of the colliding galaxies will lead to irregular shapes
resistance?
Electrical kettle:
P = 2 KW = 2000 W
U = 200 V
⇒ I = P/U = 2000 / 200 = 10 A
We apply the Law of Ohm:
R = U / I = 200V / 10A = 20 Ω
=======
Electrical heater:
P = 1 KW = 1000 W
U = 240 V
⇒ I = P/U = 1000 / 240 = 4,16 A
We apply the Law of Ohm:
R = U / I = 240V / 4,16A = 57,69 Ω
Answer:
The device with the highest resistance is the electric heater.

The rock on the ground has more kinetic energy compared to the feather floating through the air, due to the force of gravity.
Kinetic energy is the energy of motion, and a moving object has kinetic energy. Potential energy, on the other hand, comes in several forms, such as gravitational potential energy. When comparing a feather floating through the air and a rock on the ground, we can say that the rock has more kinetic energy.
This is because the rock, when dropped, falls to the ground due to the force of gravity, gaining kinetic energy in the process. The feather, on the other hand, is floating through the air and not experiencing the same gravitational pull, thus having less kinetic energy than the rock.

Acceleration = (change in speed) / (time for the change)
Change in speed = (speed at the end) - (speed at the beginning)
Change in speed = (54 km/hr) - (32 km/hr) = 22 km/hr
Acceleration = (22 km/hr) divided by (the time it takes to change the speed)
