Answer:
25 N
Explanation:
Use the equation F = m(Vf–Vi) / Δt.
average force = mass (final velocity - initial velocity) / change in time
F = 40 kg(5.0 m/s) / 8.0 s = 200 / 8.0 = 25 kgm / s^2 = 25 Newtons
Here’s the answers, down there
Answer:
180
Explanation:
because you have to multiply 9 x 20 which gives you 180 for your total
1. The correct statement that describes a Redox reaction is ( D ) ; A chemical reaction in which electrons are transferred between reactants.
2. The chemical formula that shows the correct subscripts is ( D ) BeF₂
3. The type of reaction that is shown is ; ( C ) decomposition reaction
A Redox reaction ( oxidation-reduction reaction ) involves the exchange/transfer electrons between reactants and the change in the oxidation number of the molecules involved in the reaction changes when an electron is either gained or lost.
Given that the Be has four ( 4 ) electrons and Fluorine has nine ( 9 ) electrons when they combine Fluorine will be left with an excess of electrons therefore the correct chemical formula will be BeF₂
The breaking up of an element into its smaller parts in a chemical reaction is known as a decomposition reaction.
Global warming causes the atmosphere to get heated, in turn this heat is harnessed by solar panels and then converted to electricity, this conversion process tends to restore cooling to the atmosphere according to research
<h3>Meaning Of Global warming and Solar Energy</h3>
- While Global warming can be defined as the long-term heating of Earth's climate system, which increases heat-trapping greenhouse gas levels in Earth's atmosphere.
- Solar energy is radiant light and heat from the Sun that is harnessed using a range of technologies such as solar power to generate electricity.
