Answer:
V2 = -25.93 m/s
Explanation:
First of all, we know that;
Momentum = mass x change in velocity
Thus;
Momentum = m(v2 - v1)
Also, we know that;
Impulse = force x time
And also that;
Momentum = Impulse
From the question, m = 0.145kg and V1 = 32m/s while impulse = -8.4 N.s
Thus;
0.145(v2 - 32) = -8.4
Now,
0.145v2 - 4.64 = -8.4
0.145v2 = -8.4 + 4.64
0.145v2 = -3.76
v2 = -3.76/0.145
= -25.931 m/s and to two significant figures gives -25.93 m/s
Answer:
True: The stored energy in organic matter or wastes is called biomass energy and when burned can be used to produce thermal energy used for cooking, heating homes or generating electricity.
Explanation:
For Household Needs, biomass is utilized for home heating or for cooking purposes. In that case the most common source for fuel is wood, but there are also other substances are used. Latest wood-stoves designs are made in an effective way for heating and cooking needs. With the help of those new technologies fuel consumption is decreased to a significant amount.
Humans have been using biomass energy since ages for cooking their food and heating homes by burning woods. Biomass energy can be used in homes for heating or cooking or in industries large power plants to produce electricity
What is Biomass Energy? Biomass consists of energy in stored form taken from the sun. In photosynthesis plants take energy from sun. By burning biomass the energy emitted in result can be used for heating purposes. There are many types of biomass energy made by either burning or by converting it into liquids or gas, called Bio-fuels and Bio-gas.
Summary:
No doubt Biomass contribute in air pollution formation but it is less than the pollution caused by certain gases and fossils fuels which produce sulfur resulting in acidic rain and polluting our environment.
It is E=something which leases another something equaling another something
Answer: <em>In order to calculate the mechanical advantage of a wheel and axel, you can divide the radius of the wheel by the radius of the axle. If a wheel's radius is 60cm and its axle is 30cm, what is the mechanical advantage of the wheel and axle? The output force of the wheel and axle is 2 times greater than the input force.</em>
