Answer:
2500N
Explanation:
f = m.a
m=500 kg
a=5 m/s²
f = 5*500 kgm/s² = 2500 N
Answer:
C. <u>Trans-membrane protein channels that are always open to allow K+ to cross the membrane without the additional input of energy</u>
Explanation:
As we know that K+ leakage channels indicate the Potassium leakage channel. The best characterizes about K+ leakage channels is that there is a Trans-membrane protein channel which is always open to allow K+ to cross the membrane without the additional input of energy.
Actually when a cell dies its membrane potential gets more positive and finally reaches zero .
The key point is that the cells spend energy to maintain the intra-cellular ionic concentrations constant.
The membrane permeability of K+ is much higher than the membrane permeability of Na+.
Therefore, the correct choice is option (C).
Answer:
203360Pa
Explanation:
Pressure= density of liquid*height*g
=1000*10*10
=100000Pa
Total pressure= water pressure + atmospheric pressure
=1000000+103360
=203360 Pascal
Answer:
Gravitation
Explanation:
Gravity, also called gravitation, in mechanics, the universal force of attraction acting between all matter. ... On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth's mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects.
