Answer:
(c) increase by a factor of four
Explanation:
the formular for the relationship between energy and current is E= I²Rt (Heat energy)
the heater is fairly independent of its temperature , and given the time to be constant.
with the current being doubled,
E = I² Rt
E/ I² = K
=
E2 = 
I2 = 2* I1
E2 = E1 * 4*I1² / I1²
dividing , we have that E2 = 4 * E1
which means during the same time interval the amount of energy will increase by a factor of four.
Wave speed = (frequency) x (wavelength)
= (266 /sec) x (1.3 meters)
= 345.8 meters/sec
Its often used for monuments because of its beauty and its variety of colors
Answer:
The object displacement is 0 meters.
Explanation:
Because the expression for the object position as function of time is:

At t= 3.0=t2 seconds the x-position of the object is:


and at t=1.0=t1 seconds the x-position of the objects is:


The total displacement (
) of the object between t2 and t1 is the difference between x(3.0s) and x(1.0s):


The displacement of the object is zero!!!
