Answer:
Inertia
Explanation:
People can float in space since there is no gravity. Pretty Simple? The reason why thingsvlike planets and stars don't move is due to Inertia, which keeps the things in line in the solar system.
Answer:
f = 2 f₀
Explanation:
A mass-spring system has angular velocity
w = √ k / m
The angular velocity is related to the frequency
w = 2π f
f = 1 /2π √k / m
If we change the mass for another that is ¼ of the initial mass
m = ¼ mo
We replace
f = 1 / 2π √(k 4 / mo)
f = (1 / 2π √k/m₀) √ 4
f = 2 f₀
In summary the frequency doubles from the initial frequency
Answer:
Yes.
Explanation:
With no extra force acting upon it, it is a still object.
Like laying flat on a bed of nails. With no force pushing you down besides gravity, you will not cut yourself.
Answer: aluminum chlorine and iron(lll) oxide
Explanation:
Answer:
50m; 0m/s.
Explanation:
Given the following data;
Initial velocity = 20m/s
Acceleration, a = - 4m/s²
Time, t = 5secs
To find the displacement, we would use the second equation of motion;
Substituting into the equation, we have;
Displacement, S = 50m
Next, to find the final velocity, we would use the third equation of motion;
Where;
- V represents the final velocity measured in meter per seconds.
- U represents the initial velocity measured in meter per seconds.
- a represents acceleration measured in meters per seconds square.
<em>Substituting into the equation, we have;</em>
Final velocity, V = 0m/s
<em>Therefore, the displacement of the bus is 50m and its final velocity is 0m/s.</em>
