Question: A car accelerates uniformly at a rate of 10m/s² from an initial velocity of 36km/hr for 30s. What is the covered distance during this period?

Answer:

Given data:

Acceleration of the car (a) = 10 m/s²,

Initial velocity of the car (u) = 36 km/h

Time of travelling (t) = 30 s


Step-1 To covert velocity in m/s from km/h.

As we know that 1 km/h = 1000/3600 m/s

Therefore,



Step-2 To determine distance travelled by the car within t = 30 s.
According to the equation of the constant acceleration motion. Distance travelled by the car can be written as,
 


Thus, the car will travel through 4800 m within 30 seconds.

Differences between Ideal and Real Fluids

-
  Fluids are substances that flow and take the shape of their container. In physics, fluids can be idealized as either ideal or real. The difference between these two types of fluids lies in their behavior and properties. Ideal Fluids Ideal fluids are theoretical fluids that possess perfect fluidity. They are characterized by the following properties: Inviscid: Ideal fluids have zero viscosity and do not experience friction. Incompressible: Ideal fluids have a constant density and do not change volume under pressure. Continuity: Ideal fluids follow the principle of continuity, which states that the volume flow rate remains constant at all points in a pipe or channel. Real Fluids Real fluids, on the other hand, are actual fluids that exist in the real world. They have properties that differ from ideal fluids and include: Viscosity: Real fluids have viscosity and experience friction when they flow. Compressibility: Real fluids have varying densities and change volume under pressure. ...

Question: A car has an acceleration of 6 m/s². And it is started from the rest. How long will it take to reach a velocity of 48 m/s? Answer: Given data: Acceleration of the car (a) = 6 m/s²,  Initial velocity of the car (u) = 0 m/s (because intially car is at rest) and  Final velocity of the car (v) = 48 m/s. According to the equation of the constant acceleration motion,   Thus, the time required to obtain 48 m/s velocity is 8 seconds.

Can a small force exert a greater torque than a larger force?

As shown in figure, torque is dependent on distance at where force is applied and force. It means that torque can be incresead or decreased by changing the distance or force. Let's look in to the formula of torque. Torque= Force × Distance  Now if you have two forces with different magnitudes, you can create same torque by changing distance accordingly. Let's take an example, there are two forces F' and F" as F'<F". And it is needed to torque from force F'  which is more than F",  we need to increase the distance of F'  accordingly as it creates larger torque than F".
