plz mark 5 stars, thanks, and brainliest
Doing a force balance on the car:
ma = Fr
ma = μmg
a = μg
a = 0.3(9.81)
a = 29.43 m/s2
Using the formula:
2ax = v2
2(29.43)(34) = v2
v = 44.74 m/s = 161.05 km/h
The car was going 44.74 m/s or 161.05 kph when the brakes were applied.
These are called neap tides!
Hope this helps :)
A- electric forces only - WHEN The force exerted on a stationary charged object is nonzero.
B- magnetic forces ONLY - The magnitude of the force depends on the charged object's direction of motion.
C- both electric and magnetic forces - The force is proportional to the magnitude of the charge of the object on which the force is exerted.
D- neither electric nor magnetic forces- The force exerted on a moving charged object is zero.
(vi)- The force exerted on a charged object is proportional to its speed- magnetic forces only

Answer:
0.84 cm
Explanation:
u = Object distance = 0.35 cm
v = Image distance = -0.6 cm (near point is considered as image distance and negative due to sign convention)
f = Focal length
From lens equation
Focal length of the lens is 0.84 cm
