The answer is well log data, it is a detailed log of information taken from a borehole which geologist used to study geological formations of the earth's layer taken from samples returned from the borehole which was dugged.
-- If acceleration and velocity are in the same direction,
then the object is speeding up.
-- If acceleration and velocity are in opposite directions,
then the object is slowing down.
-- If acceleration is perpendicular to velocity, then the object
is moving on a circular curve at constant speed.
Answer: m = 0.4 kg
Explanation: Momentum is the product of mass and velocity also expressed in this equation:
p = m x v
Derive to find m
m = p / v
= 10 kg•m/s / 25 m/s
= 0.4 kg
Yes
Explanation:
This chemical equation:
is balanced, because the number of atoms of each element is the same on the reactant side and on the product side. In fact:
- Mg: one atom on the left, one on the right
- I: 2 atoms on the left, and 2 on the right
- Br: 2 atoms on the left, and 2 on the right
So, the reaction is balanced.
Answer:
6.93m
Explanation:
Using the method of SOH CAH TOA
The base of the tree is 12m which is the adjacent side of the triangle to be generated, the height of the tree will be facing the angle of elevation and it is the opposite side.
Using the formula tan(theta) = Opposite/Adjacent
Given theta = 30°
Adjacent is 12m which is the distance the tree is making with the shadow on the ground
Opposite side will be the height of the tree.
Tan(theta) = height/12
Tan30° = height/12
Height = 12tan30°
Height = 6.93m
Therefore the height of the tree is 6.93m
