Answer:
v = 2591.83 m/s
Explanation:
Given that,
The electric field is 1.27 kV/m and the magnetic field is 0.49 T. We need to find the electron's speed if the fields are perpendicular to each other. The magnetic force is balanced by the electric force such that,
So, the speed of the electron is 2591.83 m/s.
An object in motion eventually stops because of friction.
<h3>What is Newton’s first law of motion?</h3>
Newton's first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or continue its moving in a straight line at constant speed unless force is applied on it.
So we can conclude that An object in motion eventually stops is the correct answer.

Answer:
P = 79993.43245
Explanation:
Được -
Vị trí tâm ống dẫn dưới đường thuỷ ngân h1 = 820 mm
Chênh lệch chiều cao của cột thủy ngân h2 = 880mm
Tỷ trọng của thủy ngân = 13,5951 g / cm3
P = mật độ * gia tốc do trọng lực a * h
Thay thế các giá trị đã cho, chúng ta nhận được -
P = 13,5951 g / cm3 * 980,665 cm / s2 * (88-82) cm
P = 79993.43245
The genes that are inside the chromosomes of the cell.
The answer is D. centripetal force
This definition of centripetal force is a force acting towards the center of an object moving in a circular motion. Acceleration is the rate of which velocity changes over a period of time. If you pick a point on say a rotating circle and find the tangential velocity at each point it goes through, the acceleration would be towards the middle.
