Answer:
Explanation:
Given
Mass = m
Time = t
Force = mass × acceleration ..... 1
Where acceleration = velocity/time
Ave Force = m×∆v/∆t
= mv/t
Answer: <em>Rotational motion</em>
Explanation: The two types of motion of the rolling ball are translational motion and rotational motion. The center of mass of the ball undergoes translational motion whereas the ball undergoes rotational motion in the center of mass frame.
Answer:
c) are economically valuable services provided by natural systems is the correct answer.
Explanation:
- Ecosystem services are methods that happen in an ecosystem.
- Ecosystem services are the abundance of advantages that nature gives to society and humankind.
- Ecosystem services make the individual life pleasant via producing nutritious food and cleaned water, controlling disease, oxygen generation, soil formation, biomass production and giving social and spiritual advantages.
Given the Hubble's constant, the approximate age of the universe is 5.88 × 10⁹ Years.
Given the data in the question;
Hubble's constant;
Age of the universe;
We know that, the reciprocal of the Hubble's constant ( ) gives an estimate of the age of the universe ( ). It is expressed as:
Now,
Hubble's constant;
We know that;
so
Therefore;
Now, we input this Hubble's constant value into our equation;
Therefore, given the Hubble's constant, the approximate age of the universe is 5.88 × 10⁹ Years.

Answer:
317.22
Explanation:
Given
Circular platform rotates ccw 93.1kg, radius 1.93 m, 0.945 rad/s
You 69.7kg, cw 1.01m/s, at r
Poodle 20.2 kg, cw 1.01/2 m/s, at r/2
Mutt 17.7 kg, 3r/4
You
Relative
ω = v/r
= 1.01/1.93
= 0.522
Actual
ω = 0.945 - 0.522
= 0.42
I = mr^2
= 69.7*1.93^2
= 259.6
L = Iω
= 259.6*0.42
= 109.4
Poodle
Relative
ω = (1.01/2)/(1.93/2)
= 0.5233
Actual
ω = 0.945- 0.5233
= 0.4217
I = m(r/2)^2
= 20.2*(1.93/2)^2
= 18.81
L = Iω
= 18.81*0.4217
= 7.93
Mutt
Actual
ω = 0.945
I = m(3r/4)^2
= 17.7(3*1.93/4)^2
= 37.08
L = Iω
= 37.08*0.945
= 35.04
Disk
I = mr^2/2
= 93.1(1.93)^2/2
= 173.39
L = Iω
= 173.39*0.945
= 163.85
Total
L = 109.4+ 7.93+ 36.04+ 163.85
= 317.22 kg m^2/s
