Answer:
Explanation:
True
Average speed is the ratio of total distance traveled to the total time taken and average velocity is total displacement to the total time.
And we know distance is either equal to or greater than displacement so we can say that for equal time interval magnitude of average velocity can never be greater than average speed.
Cardiac, smooth, and skeletal. cardiac muscle cells are located in the walls of the heart and appear striated and are under involuntary control. smooth muscle fibers are located in walls of hollow visceral organs except the heart they also appear striated. skeleton muscle is found between bones and uses tendons to connect to the epimysium to the periosteum, or the outer covering of bone. skeletal muscle is shaped and adapted in many ways.

Answer:
Explanation:
Given that
At 17°C ,Lo= 20.09 cm
At 306°C ,L= 20.18 cm
ΔL= 200.18 - 20.09 = 0.09 cm
ΔT = 306 - 17 = 289°C
We know that
ΔL = L α ΔT
α =coefficient of linear expansion
ΔL = Lo x α x ΔT
0.09 = 20.09 x α x 289
Coefficient of linear expansion,
Yes. 'Equilibrium' means that the SUM of adding up all the forces acting on the object is ZERO.
If you add up all the forces acting on the object and the sum is NOT zero, then the object is NOT in equilibrium. The force you have to add to it is whatever it takes to cancel out (balance) all the forces that are there now.
Take the SUM you got when you added up all the existing forces. To get equilibrium, ADD ON one new force with the SAME magnitude, in exactly the OPPOSITE direction.
