Answer: 225 joules.
Explanation:
If this a one dimension problem, this is the motion is in the same direction of the force, the equation for work is:
Work = distance × force
⇒ Work = 15 m × 15 N = 225 joules.
This is a special case of the general equation
Work = |F| |displacement| cosine (angle between the force and displacement)
When force and displacement are in the same direction, the angle is 0, so cos(0) = 1. This is the two vectors are parellel and the work is just the product of the two magnitudes (force and distance)
Answer:
4.816x10²⁴atoms
Explanation:
the number of moles of oxygen is 8
let x be number of oxygen atoms
recall that 1 mole=6.02x10^23 atoms
therefore, 8 moles =x
cross multiply
8 x 6.02 x 10^23 = x
x = 4.816 x 10²⁴atoms
Answer:
That is the correct form for a hypothesis.
Explanation:
Explanation:
Magnesium has atomic number 12. It will be distributed in K, L, M shell in the following way:
K shell can accommodate a maximum of 2 electrons.
L shell can accommodate a maximum of 8 electrons and
M shell will accommodate 2 electrons
So the configuration becomes 2, 8,3
The amount of CO2 in the atmosphere is increasing is true about the carbon cycle.I know why the option a wont work,because, on the off chance that they didnt spin around the sun, then they would simply be drifting around in straight lines colliding with each other.
