Answer:
Current through the surface at t = 1.1 s is 21.37 A.
Explanation:
The charge is passing through a surface of area varies with time as :
Here,
t is in seconds
The rate of change of electric charge is called electric current. It is given by :
At t = 1.1 s, Current,
So, the instantaneous current through the surface at t = 1.1 s is 21.37 A.
It's 61.5m
by solving simultaneously equations
29+d = 6t (bear)
d=4.1t (tourist)
I think the correct answer is B- heat is trapped in the earth atmosphere
To convert parametric to Cartesian systems, you need to find a way to get rid of the t's.
In this case, the t's are inside trigonometric functions, so we're going to use a very famous trig identity you should memorize:
If we plug sin(t) and cos(t) into that equation only x and y variables will be left!
BUT there's one thing. The given cos(t + pi/6) has nasty extra stuff in it. However, part a gives you a tip on how to relate x and y to a nice clean cos(t)
So if we do a little rearranging:
Now we can plug these into the famous trig identity!
Do a little bit of adjustments to get that final form asked for, and you'll be able to find those integers of a and b. ;)
Weight is force.
The metric unit of force is the Newton.
1 Newton is the force needed to accelerate 1 kilogram at the rate of 1 m/s² .
