Answer : Total electrical energy is 36000 J.
Explanation :
It is given that,
Power of electric toaster, P = 1200 Watts
Voltage, V = 120 Volts
Time, t = 30 s
Electric energy is defined as the product of the power and the time taken.
Total electrical energy used to operate the toaster for 30 seconds is 36000 J.
a) uniform velocity
b) zero or no acceleration
c) (see picture)
EXPLANATION:

Answer:
735N
Explanation:
Weight is a measurement of force.
F = Force
m = mass
a = acceleration
F = m*a
F = 75kg*9.8m/s²
F = 735N
Answer:
A plane mirror is placed to the right of an object. The image formed by the mirror will be a virtual image that appears to be on the left of the mirror.
Explanation:
The components are at a right angle so the resultant is R^2 = 4.50^2 + 9.80^2 R = 10.78 or 10.8
