Earths tilt making the sun go haywire lol XD
Answer:
W_net = mg + 2mgh/r
Explanation:
The forces applied in this motion of the bowling ball are both gravitational and centripetal forces.
Now, gravitational force is; F_g = mg
While centripetal force is; F_c = mv²/r
Since we want to express the net force in terms of the variables in the statement and we are not given "v", let's find an expression of v with the variables given.
Now, from Newton's equation of motion, at initial velocity of 0, v² = 2gh.
Thus;
F_c = 2mgh/r
Where;
m is ball mass
r is tube radius
h is fall height
Thus, the net force will be;
F_net = F_g + F_c
Now, Net force would be equal to the net weight that will be read on the scale.
Thus;
W_net = F_net = F_g + F_c
W_net = mg + 2mgh/r
Answer:
Explanation:
kinetic energy involves motion and potential energy involves position. Which of the following energy forms is associated with an object due to its position relative to Earth
Answer:
Yes, Most living thing need oxegen, plants need light to grow(food).
plants and animals need water. temputre is important too, most living things need a tempure range. therefor, all(most) living things need these 5 thing to live.
just rewrite this in your own word
Hope this helped you

Answer:
90 miles
Explanation:
speed = 30 miles per hour, time = 3 hour
The formula for the speed is given by
speed = distance / time
Distance = speed x time
distance = 30 x 3 = 90 miles
