Answer:
The value of resistance of each resistor, R is 2.25 Ω
Explanation:
Given;
voltage across the three resistor, V = 1.5 V
power dissipated by the resistors, P = 3.00 W
the resistance of each resistor, = R
The effective resistance of the three resistors is given by;
R(effective) = R/3
Apply ohms law to determine the current delivered by the source;
V = IR
I = V/R
I = 3V/R
Also, power is calculated as;
P = IV
P = (3V/R) x V
P = 3V²/R
R = 3V² / P
R = (3 x 1.5²) / 3
R = 2.25 Ω
Therefore, the value of resistance of each resistor, R is 2.25 Ω
As the stan moves 0.94 s before with an acceleration 4.12 m/s^2
so the distance moved by it
![d = \frac{1}{2}at^2[tex]d = \frac{1}{2}*4.12*0.94^2](https://tex.z-dn.net/?f=d%20%3D%20%5Cfrac%7B1%7D%7B2%7Dat%5E2%3C%2Fp%3E%3Cp%3E%5Btex%5Dd%20%3D%20%5Cfrac%7B1%7D%7B2%7D%2A4.12%2A0.94%5E2)

speed gained by the car is given as


now the relative speed of them is given as

relative acceleration is given as

now the distance between them is to be covered


by solving above equation we have

so it will overtake after 6.64 s
Answer:
And return to their normal position after the wave passes.
Explanation:
Even though their positions are changed drastically after the wave in a medium, they eventually return to their original positions.
Hope this Helps!
Answer:
false
Explanation:
Elastic collision: the collision is said to be elastic if the kinetic energy is conserved during the collision.
If the kinetic energy is not conserved, then the collision is not elastic.
So, here no information is given so we cant say about the type of collision.
So, it is False.
Answer:
The system's kinetic energy changes by 3.6 J
Explanation:
The given parameters are;
The number of cart = 2
The mass of each cart = 0.5kg
The initial length of the spring = 0.50 m
The final length of the spring =T0.3 m
The change in position of the first cart = 0.6 m
The energy given to the first cart = Work done by the force = Force × Displacement
The initial kinetic energy of the two cart moving together = Energy given to the first cart = 6.0 × 0.2 = 1.2J
The kinetic energy given to the two cart combined = The applied force × The total displacement of the two cart as they move together
The kinetic energy given to the two cart combined = 6.0 × (0.6 - 0.2)
The kinetic energy given to the two cart combined = 6.0 × 0.4 = 2.4 J
The total kinetic energy given to the two cart = 1.2 + 2.4 = 3.6 J
The total kinetic energy given to the two cart = 3.6 J
The system's kinetic energy changes by 3.6 J.
