Work is = to force*displacement which give W=F*d so if 0 force is put on an object the W= 0*d = 0 work, so a is out. for b if force is put on the object but it does not move then W=F*0 (no displacement)= 0 so if there is no movement then no work is done so b is out. for D since W=F*d also says no force is put on the object so W=0*d which would equal 0 work so D is also out. but for c W=F*d and if we assume that F is not = to 0 and d is not equal to 0 then the equation W=F*d would give a number other than 0 so only c will result in a nonzero value for work. in all other cases no work is done. As a side note if a force is applied to an object and the object goes around the world and ends up and the same place that it started then since Work is equal to force * displacement there will still end up with no work being done since W=F*0=0 work (since the object ended up in the same place it started even though it moved the displacement is still 0, so work done will still be 0.
Answer:
(a) The equivalent resistance is 18.06 Ω
(b) The current in each resistor is 0.665 A
Explanation:
Given;
first resistor, R₁ = 2.25 Ω
second resistor, R₂ = 5.90 Ω
third resistor, R₃ = 9.91 Ω
Equivalent resistance;
2.25 Ω + 5.90 Ω + 9.91 Ω
18.06 Ω
The current in each resistor;
For series connection, current is the same in every resistor.
V = I(R₁ + R₂ + R₃)
Answer: 4
Explanation:
The dependent variable is the temperature of the water.
Answer:
There are several reasons for the extinction of species. Some of these can include climate change, natural disasters, environmental destruction, or over-hunting. All of these factors can contribute to the deaths of various animals which ultimately leads to extinction if left unchecked.
