Answer:
Option D
Explanation:
Taking 2020 unit test for edu right now.
We Know, F = m*a
Here, F = 10 N
m = 1 Kg
Substitute their values in the equation,
10 = 1 * a
a = 10/1
a = 10
So, your final answer & the acceleration of the object would be 10 m/s²
Hope this helps!
Answer:
= 1.7 Joules
Explanation:
The electrical potential energy is given by;
P.E = 1/2 ke²
Where, k is the spring constant, e is the extension
Therefore;
Electrical potential energy = 1/2 × 113 N/m × 0.03 m
= 1.695 Joules
<u>= 1.7 J</u>
Answer:
8.67807 N
34.7123 N
Explanation:
m = Mass of shark = 92 kg
= Density of seawater = 1030 kg/m³
= Density of freshwater = 1000 kg/m³
= Density of shark = 1040 kg/m³
g = Acceleration due to gravity = 9.81 m/s²
Net force on the fin is (seawater)

The lift force required in seawater is 8.67807 N
Net force on the fin is (freshwater)

The lift force required in a river is 34.7123 N
They’re right that is the answer
