The correct formula for calculating the tangential speed of an orbiting object is V(t)=wr.
V(t)= Tangential Speed
w= Angular Velocity
r= Radius of the Path
Hope this helps.
Answer:
T = 15.03°C
Explanation:
given data:
copper specific heat = Sc = 0.385 J/g °C
iron specific iron = Si = 0.450 J/g °C
specific heat of ethanol = Se = 2.46 J/g °C
net heat loss is equal to zero
T = 15.03°C
There is no factor on your list of choices that has any effect.
The displacement of the object that moved 4 meters north, then 3 meters east is 5 meters.
<h3>
What is displacement?</h3>
Displacement is change in the position of an object. It can be described as the shortest distance between the initial and final position of an object.
The displacement of the object is calculated as follows;
d² = 4² + 3²
d² = 25
d = 5 m
Thus, the displacement of the object that moved 4 meters north, then 3 meters east is 5 meters.

Use direct proportionality: If 1.25 m = 72 N, then 0.55 m = y
0.55 m × 72 = 39.6.
39.6÷1,25 gives you your answer which is 31.68 N.
