I believe the answer is free electrons
Answer: a= 37m
Explanation: V= 15 m/s (Velocity) t= 0.41s (time) formula: a= v/t
15 m/s / 0.41 (15 divided by 0.41) = 36.583m
There are 2 significant digits, 36, you look at the third digit, either round up or down in this case up to 36. a= 37m
Answer:
Explanation:
Let's assume that an object is launched straight upward in a gravitational field. Its initial kinetic energy is given by
(1)
where m is the mass and v is the initial speed.
As the object goes higher, its kinetic energy decreases and it is converted into gravitational potential energy, since the total mechanical energy (sum of kinetic and potential energy) must remain constant:
At the highest point of the trajectory, the speed of the object is zero (v=0), so the kinetic energy is also zero (K=0), which means that all the kinetic energy has been converted into potential energy:
(2)
where g is the gravitational acceleration and h is the maximum height of the object.
Due to conservation of energy, we can write that (1) and (2) are equal, so:
from which we can derive an expression for the maximum height reached by the object
Answer:
Sun
Explanation:
Any asteroid in space is a celestial body. Classification of Celestial Bodies. A star is a form of a celestial object made up of a shining spheroid of plasma held together by its own gravity. The nearby star to Earth is the Sun.
Answer:
It will take 6.1seconds for the projectile to hit the ground.
Explanation:
In projectile, the time taken by an object to spend in air is its time if flight.
Time of flight = 2Usin(theta)/g
where u is the initial velocity = 75m/s, theta = 24°, g = 10m/s²
Time of flight = 2(75)sin24°/10
Time of flight = 150sin24°/10
Time of fight = 6.1seconds.
This means that it will take 6.1seconds for the projectile to hit the ground.
