Answer:
If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, there is no net water movement, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.
hope this helps!!!
Answer:
The difference in atomic mass between the two isotopes is 1.002780942 atomic mass unit.
Explanation:
For an isotope-I (heavier)
Mass of an isotope-I=M
Number of neutrons = n+1
Number of protons = p
For an isotope-II
Mass of an isotope-II=M'
Number of neutrons = n
Number of protons = p
Difference in binding energy:
(general binding energy expression)
Binding energy difference between two isotopes:
..(1)
B.E-B.E'=5.4810 MeV
Explanation:
Momentum before collision:
(2 kg) (4 m/s) + (5 kg) (-3 m/s) = -3 kg m/s
No external forces act on the balls, so momentum is conserved. Therefore, momentum after collision is also -3 kg m/s.
Answer:
The answer would be Increase becaause the springs constantmotion is increasing.
Explanation:
Answer:
I = 3.42 A
Explanation:
Ohm's law gives a relationship between the potential difference and the current passing through a conductor. The formula of Ohm's Law is given as follows:
V = IR
where,
V = Voltage
I = Current
R = Resistance
Initially:
V = 14 volts
I = 4 A
R = ?
Therefore,
14 volts = (4 A)R
R = (14 volts)/(4 A)
R = 3.5 Ω
Now, when V becomes 12 volts and R remains constant:
V = IR
12 volts = I(3.5 Ω)
I = (12 volts)/(3.5 Ω)
<u>I = 3.42 A</u>
