The correct answer is D. for sure.
Answer:
1) in the direction of the applied force
2)when the movement is not in the direction of the applied force it is not work. But if a component, or part of the motion is in the direction of the applied force it is work.
3)Joules/sec
4)Force/displacement
6)Wedges and lever
5)conduction
6)radiation
7)there is no heat flow
8)The average kinetic motion of the particles increases, there is more thermal energy
9)The average kinetic motion of the particles decreases, there is less thermal energy
10)transverse wave
11) sound waves
12)they transfer energy through oscillations in matter
13)the speed of the pitched baseball
14)to detect speed and direction of blood flow
15)green and violet are reflected and red is absorbed
16)visible light
17)as heat
18)infrared light/infrared energy
19)reflection
20) yes, the forces emitted by having the same charge repells them.
21)the flow of electrons
22)You open the circuit and the electrons can't flow
23)You closed the circuit and the electrons can flow
24)I think you meant bipolar, this means 2 poles
A chemical reaction happens
Answer and Explanation:
In crickets, femur length represents a highly important trait associated with jumping performance - an essential behavior for their survival and reproduction.
According to research, these are the possible advantages and disadvantages in regard to long femur length:
Advantages
- Longer legs [may] provide higher power for the muscles in order to jump.
- Long-legged crickets generate lower reaction forces while performing a jump, which enables them to lose less energy in comparison with crickets with shorter femur length.
Disadvantages
- Longer femurs may increase the total take-off time of a cricken prior to a jump.
- In some cases, longer femurs force insects to develop head or body structures to enable them to 'fit' the legs while they prepare to jump.
- Increased energy loss while jumping from an elevated leaf.
