A boat moves initially at 10 m/s, then accelerates at 2 m/s^2 for 10 s. What is the velocity of the boat after 10 s?

Answer:

30 m/s

Explanation:

A boat moves initially at 10 m/s

The boat accelerates at 2 m/s^2 for 10 seconds

We are required to calculate the final velocity (v)

Therefore the velocity of the boat can be calculated as follows

v = u + at

u= 10 m/s

a= 2 m/s^2

t= 10 seconds

v= 10 + 2(10)

v= 10 + 20

= 30 m/s

Hence the velocity of the boat after 10 seconds is 30 m/s

Give two examples of Newton's second law of motion
romanna [79]
<span>Examples of Newton's 2nd Law  If you use the same force to push a truck and push a car, the car will have more acceleration than the truck, because the car has less mass.  It is easier to push an empty shopping cart than a full one, because the full shopping cart has more mass than the empty one.</span>

How can parallax allow us to determine the distance to a star
tensa zangetsu [6.8K]

Answer:

Astronomers use a method similar to the one you used with your homemade quadrant. Twice the distance to the Sun, divided by the distance to the star (which is unknown so far) is equal to the tangent of the parallax angle of the star.

Current flowing in a circuit depends on two variables. Identify these variables and their relationship to current.
Nuetrik [128]
Wow ! This question reads like it might have come from one of
Faraday or Maxwell's original laboratory notebooks.

Choice-A is the correct one, when you consider what "conductance"
means. Conductance is just 1/resistance .

So when you see
"A) Current is proportionate to the conductance of the circuit and
precisely proportional to the voltage applied across the circuit."

what it's saying is
"Current is inversely proportional to the resistance of the circuit, and
directly proportional to the voltage applied across the circuit."

If you write the equation for all those words, it looks like

I = V / R

and that's correct.
