The chemical reaction of Cavendish involving zinc would be a reaction between hydrochloric acid and zinc yielding zinc chloride and hydrogen gas.
Answer:
Significant digits (also called significant figures or “sig figs” for short) indicate the precision of a measurement. A number with more significant digits is more precise. For example, 8.00 cm is more precise than 8.0 cm.
Answer:
the peak wavelength when the temperature is 3200 K =
Explanation:
Given that:
the temperature = 3200 K
By applying Wien's displacement law ,we have
T = 0.2898×10⁻² m.K
The peak wavelength of the emitted radiation at this temperature is given by
=
=
Hence, the peak wavelength when the temperature is 3200 K =
The radius of the mass sphere M = R
2M = 2R
Distance between the centre of the sphere = 12 R
Separation between the centres = R + 3R = 4R
a) Conservation of linear momentum and the mechanical energy of the system
<h3>How do you explain conservation of linear momentum?</h3>
The conservation of momentum is a essential concept of physics in conjunction with the conservation of energy and the conservation of mass. Momentum is described to be the mass of an item accelerated with the aid of using the rate of the object. The conservation of momentum states that, within a few hassle domain, the amount of momentum stays constant; momentum is neither created nor destroyed

Answer:
15 km/s from the starting point
Explanation:
Velocity is total distace divided by total time.
From the picture, you can see that line consecutively traveled 30 kilometers- in 2 seconds.
(9 to 11 is two seconds, unless I'm wrong.)
So, total distance = 30 km. Total time = 2 seconds.
30/2 is 15.
the velocity of line A is 15 km/s from the starting point.
