Geothermal and nuclear energy are derived from radioactive materials.
Wave energy, from the ocean, is derived from winds blowing over the ocean, which are derived from the Sun's uneven heating of the earth.
Biomass energy is from plants, which get energy through photosynthesis, derived from the Sun.
Answer:
1.) Liquid
2.) Low
3.) Molecular
4.) Surface tension
5.) Solvent
Explanation:
Water is important to living things because it remains in the LIQUID state over a wide range of temperatures. Water in lakes and oceans does
not experience large temperature changes because liquid water has a
LOW specific heat, so it must absorb or release a lot of energy as its temperature changes. The MOLECULAR forces between water
molecules cause water to form round droplets and cause water's high SURFACE TENSION. Water is also an important SOLVENT because it can
dissolve many different substances.
Answer:
8) A hanging 7.5 kg object stretches a spring 1.1 m. What is the spring constant? 1 . 1 66. 82 NIMO 9) A spring has a constant of 875 N/m. What hanging mass will cause this spring to stretch 4.5 m? Iouliply then divide 875 X 4. 2- - (4 04. 7919) 10) A spring with a spring constant of 25 N/m is stretched 65 cm. What was the force used? 11) A 25 N force stretches a spring 280 cm. What was the spring constant? 12) A 75 N force stretches a spring 175 cm. What was the proportionality constant? 8) 66.82 N/m 9) 401.79 kg 10) 16.25 N 11) 8.93 N/m 12) 42.86 N/m
Explanation:
Answer:
13.4 m/s
Explanation:
Write down what you have, so:
V0=8 m/s
a=2.7 m/s^2
t=2 seconds
We are trying to find final velocity, so we will use vf = v0 + at
From there, we plug in the given values.
vf = 8 m/s + (2.7 m/s^2 x 2 seconds)
vf = 13.4 m/s
Answer:
Option C
Explanation:
According to the question:
Force exerted by the team towards south, F = 10 N
Force exerted by the opposite team towards North, F' = 17 N
Net Force,
Thus the force will be along the direction of force whose magnitude is higher
Therefore,
towards North
