Below is an attachment containing the solution.
The electrical energy consumed by a toaster is 0.033 Kwh.
<u>Explanation</u>:
The power utilized by the toaster is 400 W.
The toaster is operated for 5 Minutes.
We know that,
Substitute the values in the above formula to obtain electrical energy,
Electrical energy = 0.4 × 0.083
Electrical energy is 0.033 Kwh.
Answer:
0.85m
Explanation:
Given parameters:
Height of fall = 3.5m
Unknown:
Duration of fall = ?
Solution:
To solve this problem, we apply the right motion equation.
Since we know the height, we can use the equation below;
S = ut +
S is the height
u is the initial velocity = 0m/s
t is the time
g is the acceleration due to gravity
3.5 = 0 + x 9.8 x t²
3.5 = 4.9t²
t² =
t² = 0.71
t = √0.71 = 0.85m
