For an airplane whose speed is 60 m/s is flying at an altitude of 500 m over the ocean toward a stationary sinking ship, the horizontal distance is mathematically given as
x=606m
<h3> What horizontal distance from the ship should the crew of the airplane drop a pump into the water next to the ship?</h3>
Generally, the equation for the y axis distance is mathematically given as
y=vt+0.5gt^2
Therefore
500=0t+1.2(9.8)t^2
t=10.1s
In conclusion, the horizontal distance
x=vt
x=60*10.1
x=606m

Answer:
Part a)
Part b)
here we know that L = length of the wire
Explanation:
Part a)
Current density is given as
since current is uniformly divided across the crossection of the wire so it is given as
Part b)
As we know that volume current density is inversely proportional to the distance from the axis
So we will have
so we have
here we know that L = length of the wire
Answer:
Layer A is the oldest
Explanation:
The image to the left shows an undisturbed sedimentary sequence and we can use it as our type section. The layers have fossils that can be used to correlate them with other terrane. Here, layer A is at the bottom.
After the geologic event which overturns the rock layers, we see that layer A has come on top and the whole sequence has subsided.
Applying the law of superposition of strata, which states that "in an undisturbed sequence of sedimentary rocks, the oldest rock layer is at the bottom of the sequence".
Using this law, we see that layer A must have formed first D being the youngest.
Answer:
It ultimately helps you focus on your long-term goals
Explanation:
Answer:
Part a)
Part b)
Part c)
Explanation:
As we know that the net torque on the wheel is given as
now we know that its angular speed changes from 0 to 10 rad/s in time interval of 6.00 s
so we have
Part a)
We know that the relation between torque and angular acceleration is given as
Part b)
Now the angular speed will reduce to zero after removing external torque in t = 60 s
now we have
so frictional torque is given as
Part c)
Number of revolutions are given by the equation
