Answer: a = 200 Ω, b = 7.5 mA
Explanation:
Re = 100 + 100 = 200 Ω
I = E/R = 1.5/200 = 0.0075 A
Answer:
Explanation:
All living organisms are made up of cells.
Cells are the fundamental unit of life in all organisms. They perform the basic life functions required of all living organisms.
- Unicellular organisms are made up of just a single cell
- Multi-cellular organisms have more than one cell.
They are the building block of life through which other life organisations are derived.
From the choices, any living organism should have cells.
Answer:
The expression for the time taken by an object to move with a speed at some distance is,
t=<u> </u><u>d</u><u>/</u><u>v</u>
Here, t is the time taken by the opponent to react, d is the length of the court, andis the speed of the ball.

Answer:
14.0 cm
Explanation:
Draw a free body diagram of the block. There are three forces: weight force mg pulling down, elastic force k∆L pulling down, and buoyancy ρVg pushing up.
Sum of forces in the y direction:
∑F = ma
ρVg − mg − k∆L = 0
(1000 kg/m³) (4.63 kg / 648 kg/m³) (9.8 m/s²) − (4.63 kg) (9.8 m/s²) − (176 N/m) ∆L = 0
∆L = 0.140 m
∆L = 14.0 cm
