Answer:
Ellipse
Explanation:
Most comets have an elliptical path of orbit.
(I'm not sure what the unit "m1" is. Do you mean ml for milliliters? I am going to use ml in this problem.)
Volume= 130ml
Mass= 585g
The formula for density is
Density=Mass/Volume
All you have to do is pop the information in the formula Density= 585g/130ml
585/130= 4.5
you can't divide g/ml, so just leave it the way it is
Therefore the answer is
Density= 4.5 g/ml
Hope this helps!
The lower limit that could be used to determine the position of each object along the direction of the velocity is 1.136 x 10⁻³ m.
<h3>
Uncertainty in the position of the electron</h3>
The uncertainty in the position of the electron is calculated as follows;
where;
- h is Planck's constant = 6.63 x 10⁻³⁴ Js
- m is mass of electron
- Δv uncertainty in velocity = (0.01 x 10⁻²) x 510 = 0.051 m/s
Thus, the lower limit that could be used to determine the position of each object along the direction of the velocity is 1.136 x 10⁻³ m.

#SPJ1
Answer:
(a) (1) -32ft/s
(2) -25.6ft/s
(3) -24.8ft/s
(4) -24.16ft/s
(b) -24 ft/s
Explanation:
First of all, we need the position for every instant mentioned in order to calculate average velocities:
Y(2) = 2 ft
Y(2.5) = 0 ft
Y(2.1) = 13.44 ft
Y(2.05) = 14.76 ft
Y(2.01) = 15.7584 ft
Let's now calculate average velocities:
Now, for the instantaneous velocity, we derive the expression for y:
V(t) = 40 - 32t For t=2s V(2) = -24ft/s
