Find the instantaneous velocity at time 𝑡1=1.0 𝑠 using the equation 𝑥=20 𝑚+(5.0𝑚/𝑠^2)𝑡^2 during the time interval between t1=1.0 s and t2=2.0 s
The capacitors have values C1 = 2.5 µF and C2 = 4.0 µF, C3 =
6.0 µF C4 = 8.0 µF and the potential difference across the battery is
12.0 V. Assume that the capacitors are connected in series. Find the
equivalent capacitance of the circuit and solve for the potential
difference across each capacitors.
Determine the electrical force of attraction between two balloons that are charged with the opposite type of charge but the same quantity of charge. The charge on the balloons is 6.6 x 10^-5 C and they are separated by a distance of 150 cm.
A point charge (Q1) has a magnitude of -7 uC. A second charge (Q2) has a magnitude of -5.5 uC and is located 143 cm from the first charge. Find the magnitude of the force between the two charges.
Two balloons are charged with a different quantity of charge: balloon A with 5 nC and balloon B with 4 nC. They are held apart at a separation distance of 3.5 meters. Determine the magnitude of the electrical force of repulsion between them.
Determine the electrical force of attraction between two balloons with separate charges of +4.5 x 10^-8 C and -1.9 x 10^-8 C when separated a distance of 0.95 m.
If the angle of incidence of a ray of light on a plane mirror is 40°, the deviation of the incident ray after reflection is
An object is in equilibrium if all the forces on it balance. The figure below shows a beam weighing 124 N that is supported in equilibrium by a 100-N pull and a force at the floor. The third force on the bean is the 124-N weight that acts vertically downward.
