Answer:
critical value is known as threshold
Explanation:
solution
when we apply electrical stimulus to the cell of muscle
then magnitude of stimulus will be strong enough for reaching the critical value
and this critical value is threshold because when the size of an stimulus change in requirement for the detection, this is called the threshold
but if change is done by without stimulation then there threshold stimulus is absolute threshold
so correct answer is threshold
the correct answer is D- Acceleration depends indirectly on the mass.
According to Newton's second law, the force F, the mass m and the acceleration a are related as follows:
Therefore,
The acceleration <em>a₁ </em>of the mass<em> m₁ =1 kg</em> is given by,
The acceleration <em>a₂ </em>of the mass <em>m₂=10 kg</em> is given by,
The smaller mass has greater acceleration.
Thus, when the force applied on two bodies of different masses remains constant, then,
Acceleration is inversely proportional to the mass of the body.
Air resistance is type of contact force as the air should be in contact with the surface of moving
object to ocure air resistance.
Answer:
For C1, Q = 1.6125×10⁻³ C
For C2, Q = 6.25×10⁻⁴ C
Explanation:
Note: Since the capacitors are connected in parallel, The voltage across each of them is equal.
From the question,
Q = CV........................ Equation 1
Where Q = Charge on the capacitor, V = Voltage across the capacitor, C = Capacitance of the capacitor.
For the first capacitor,
Q = C1V............. Equation 2
Where C1 = 6.45 μF= 6.45×10⁻⁶ F, V = 250 V
Substitute into equation 2
Q = (6.45×10⁻⁶ )(250)
Q = 1.6125×10⁻³ C.
For the the second capacitor,
Q = C2V............. Equation 3
Given: C2 = 2.50 μF = 2.5×10⁻⁶ F, V = 250 V
Q = (2.5×10⁻⁶ )(250)
Q = 6.25×10⁻⁴ C
