Answer:
98m/s
Explanation:
Given parameters:
Time = 10s
Unknown:
Final speed = ?
Solution:
To solve this problem, we use the expression below;
v = u + gt
v is the final velocity
u is the initial velocity = 0m/s
g is the acceleration due to gravity = 9.8m/s²
t is the time
so;
v = 0 + 9.8 x 10 = 98m/s
Answer:
4.93 m
Explanation:
According to the question, the computation of the height is shown below:
But before that first we need to find out the speed which is shown below:
As we know that
= 9.92 m/s
Now
98.4064 = 19.96 × height
So, the height is 4.93 m
We simply applied the above formulas so that the height i.e H could arrive
Answer:
in a microscope the place you keep your eyes to observe
Answer:
40.5 N
Explanation:
second law of newto says : F = ma
F= 4.5 × 9 = 40.5 N
Electric generator is a device that converts mechanical energy obtained from an external source into electrical energy as an output. It was discovered that the above flow of electric charges could be induced by moving an electrical conductor such as a wire that contains electric charges in a magnetic field
