Calculate the change in internal energy when the system absorbs 350J of heat and performs 330 J of work.

d: the voltage of the secondary coil is less than that of the primary coil.

im not suree sorry if wrong

(b) which contains higher levels of vitamin b, oranges or spinach?

explanation:

you can eliminate a, c, and d because they are questions based on opinions.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
