Answer:
3.round object that orbits the Sun but lacks the ability to clear the neighborhood around its orbit.
Explanation:
in 2006 the IAU, said that a dwarf planet is round object that has not cleared the area round a object and that is why Pluto, Ceres, and Eris are dwarf planet.
Explanation:
1.
We use the equation
h =
, where
h is the height traveled,
g is the acceleration due to gravity and
t is the time taken to reach height h.
We can now calculate t to be
![\sqrt{\frac{2*1.2 m}{9.81 m/s^2} }](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7B2%2A1.2%20m%7D%7B9.81%20m%2Fs%5E2%7D%20%7D)
= 0.495 s
Let v be the initial velocity of the player.
The player deaccelarates from v m/s to 0 m/s in 0.495 s at the rate of 9.81 m/s^2.
v = 9.81 m/s^2 x 0.495 s = 4.85 m/s
2.
The player takes 0.3 s to increase his velocity from 0 m/s to 4.85 m/s. So his average accelaration is
4.85 m/s / 0.3 s = 16.2 m/s^2
Answer:
Option 1 is correct.
The current passing through the brighter bulb is larger.
Explanation:
The brightness of the bulb is determined by the power, I²R
And since they all have equal resistances, the only factor different that could result in more or less power is the current, I through the bulb.
Acceleration occurs whenever the forces on an object are unbalanced.
It's the group of forces on the object that's either balanced or unbalanced.
There's no such thing as "an unbalanced force".
