A 1490-kg car is moving due east with an initial speed of 29.5 m/s. After 9.14 s the car has slowed down to 18.8 m/s. Find the m

Answer:

The magnitude of the net force that produces the deceleration = 1744 N

Explanation:

Using the equations of motion, we can find the deceleration of the car and thereby find the magnitude of the met force that produces such deceleration

v = u + at

where v = final velocity = 18.8 m/s

u = initial velocity = 29.5 m/s

t = 9.14 s

a = ?

v = u + at

18.8 = 29.5 + 9.14a

9.14a = 18.8 - 29.5 = -10.7

a = - 1.171 m/s²

Magnitude of Force causing deceleration = ma = 1490 × 1.171 = 1744 N

Sphere A has a charge of +2 x 10 to the power of -6 coulomb and is brought into contact with a similar sphere, B which has a cha
Setler [38]
When sphere A and B are brought in contact and separated, charge on each sphere becomes [2x10^-6 + (-4x10^-6)]/ 2 = -1x10^-6 C.

That is, charge is equally separated and is the average of charges on both spheres. The reason behind equal charge on both spheres after separation is, when they are kept in contact, their potential difference becomes same.

Desde el punto A sale un vehículo a 80 km/h al mismo tiempo sale un ciclista a 20km/h ¿a qué distancia se encuentra uno del otro
stiv31 [10]

Answer:

Distance between them after 5 hours is 300 km.

Explanation:

From point A a vehicle leaves at 80 km / h at the same time a cyclist leaves at 20 km / h at what distance is they from each other after 5 hours.

Distance traveled by A in 5 hours = speed x time = 80 x 5 = 400 km

Distance traveled by B in 5 hours = speed x time = 20 x 5 = 100 km

The distance between them after 5 hours =  400 - 100 = 300 km
