Answer:
The speed of the particle is 34.66 m/s.
Explanation:
Given that,
Mass of particle = 50 g
Charge of particle = 4.0 mC
Velocity = 25 m/s
Electric field = 60 N/C
Time = 5.0 sec
We need to calculate the speed in y direction
Using formula of speed
Where, a = acceleration
Put the value in to the formula
We need to calculate the speed of the particle
Put the value into the formula
Hence, The speed of the particle is 34.66 m/s.
Answer:
Meteoroid , meteor and meteorite
Explanation:
A meteoroid is a small rocky or metallic body travelling through space. Most are fragments from comets or asteroids
The visible streak of light from space debris is the result of heat as it enters a planet's atmosphere, and the trail of glowing particles that it sheds in its wake is called a meteor, or colloquially a "shooting star" or "falling star". A series of many meteors appearing seconds or minutes apart, and appearing to originate from the same fixed point in the sky, is called a meteor shower. Incoming objects larger than several meters (asteroids or comets) can explode in the air. If a meteoroid, comet or asteroid or a piece thereof withstands ablation from its atmospheric entry and impacts with the ground, then it is called a meteorite.
E=274J
h=140cm=1,4m
g≈9,8m/s²
m=?
E=mgh
m=E/gh=274J/9,8m/s²*1,4m≈20kg

Answer:
the answer is 11 N left
Explanation:
there is more force being applied in the direction left, so the ball will move left. to find the net force that the ball will move in that direction subtract the force being applied in the opposite direction. so, 16N-5N=11N. your answer in 11 N left.
The correct option is B.
Sunglasses are designed to block polarized light. If you are driving toward the sun, most of the sun's glare will be coming to you horizontally, thus, the best sunglasses to wear is the one, that will block the horizontal glare and allow only the vertical glare to pass through.
