Answer:
maximum acceleration will be
Explanation:
We have given that mass of the box m = 29 kg
Coefficient of static friction
Acceleration due to gravity
For maximum acceleration
So acceleration will be
So maximum acceleration will be
Answer : The correct option is, (D) Surface tension is caused by cohesion between water molecules on the surface.
Explanation :
Surface tension : It is caused by the cohesion between water molecules on the surface or we can say that it is a tension of the surface of liquid caused by the attraction of the particles which are present on the surface layer by the bulk of the liquid, which tends to minimize surface area.
And due to the surface tension phenomena the shape of the water molecule tend to assume a spherical shape to attain the minimum surface area.
Hence. the correct option is, (D) Surface tension is caused by cohesion between water molecules on the surface.

Answer:
The amount of time is 31.45 sec.
Explanation:
Given that,
Voltage = 10.0 V
Resistance
Capacitance
We need to calculate the time constant
Using formula of time constant
Put the value into the formula
The amount of time required for the current in the circuit to decay to 4.00% of its original value.
We need to calculate the amount of time
Using formula of charge
Put the value into the formula
Hence, The amount of time is 31.45 sec.
Explanation:
because there is no air to communicate
