Answer:
1440 W
Explanation:
The power drawn by a voltage source is the rate of energy consumed, and it can be written as:
where
V is the voltage
I is the current
P is the power
For the source in this problem we have:
I = 12 A is the current
V = 120 V is the voltage of the source
Solving for P, we find the power:
Answer:
A. we will see that the notion which denotes Stephen Curry illustrates that Stephen Curry minigolf ball shot is closer
B. Lebron James hits at an angle of 17.48° North -East.
The direction of Stephen is = 20° due to East of North
Explanation:
Let represent the position vector of the hole;
Also; using the origin as starting point. Let the east direction be along the positive x axis and the North direction be + y axis
Thus:
=
=
Let be the position vector for Lebron James's first shot
So;
=
Let be the position vector for Stephen Curry's shot
=
However;
Also;
Thus; from above ; we will see that the notion which denotes Stephen Curry illustrates that Stephen Curry minigolf ball shot is closer
B .
For Lebron James ;
The angle can be determine using the trigonometric function:
Thus Lebron James hits at an angle of 17.48° North -East.
For Stephen Curry;
The direction of Stephen is = 90° - 70° = 20° due to East of North
Among the choices, the correct answer is D. "A bimetallic strip bends so that the steel is on the outside curve."
A bi-metallic strip is composed of 2 metals with different thermal coefficients. One side (usually brass) expands much faster than the other side (usually iron or steel). When brass is on the outside curve, then it means that the temperature has risen. If steel is on the outside curve, then it means that the temperature has dropped.
Answer:If you add a proton to the atom, it becomes beryllium (atomic number = 4).
It is an ion with a +1 charge, since the number of protons (4) no longer equals
the number of electrons (3).
So you have a beryllium +1 ion - the best answer choice is C.
