Answer:
a = 1.962 m/s²
Explanation:
The frictional force applied on the car can be given by the following formula:
where,
f = frictional force = ma (according to Newton's Second Law)
μ = coefficient of friction = 0.2
R = Normal Reaction = Weight of car = mg
Therefore, equation becomes:
where,
a = maximum acceleration = ?
μ = coefficient of friction = 0.2
g = acceleration due to gravity = 9.81 m/s²
Therefore,
<u>a = 1.962 m/s²</u>
Answer
given,
mass of jogger = 67 kg
speed in east direction = 2.3 m/s
mass of jogger 2 = 70 Kg
speed = 1.3 m/s in 61 ° north of east.
jogger one
now
P = P₁ + P₂
magnitude
the angle is north of east
Hot water, as in very hot water, goes to steam with an enormous change in volume and pressure. This is capable of driving turbine blades, which in turn rotate enormous copper (eg) wired coils in enormous magnetic fields. This in turn produces electricity via electromagnetic induction and Fleming's right hand (I think it is) DYNAMO rule. That goes down miles and mile of v heavy conducting wire/cable as electricity.
Answer: ZnSO4 + Li2CO3 = ZnCO3 + Li2SO4 - Chemical Equation Balancer
Equation is already balanced.
Explanation: ZnSO4 + Li2CO3 = ZnCO3 + Li2SO4
Answer:
The effect of this rotation on the person on the surface is the sky is moving, like an apparent diurnal motion.
Explanation:
<em>For an observer at a fixed position on Earth, the rotation of earth makes it appear as if the sky is revolving around the earth. In other words, if a person is standing for long enough in a field at night, it looks like the sky is moving, not the person. This motion is called "apparent diurnal motion." </em>
<em>Diurnal means having to do with a day, in a sense of a 24- hour period.</em>
