Convection cell that occurs at the lowest latitudes is called the Hadley cells. This is an atmospheric convection cell which is large-scale. The air rises at the equator and sinks at the medium latitudes which are 30 degrees north or south.
The total thermal power generated by this plutonium source is determined as 5.65 J/s.
<h3>Total thermal power generated</h3>
The total thermal power generated by this plutonium source is determined as follows;
ΔP = Eλ
where;
- E is the energy of the particles = 5.6 mev
- λ is the activity of the plutonium, which should be = 6.3 x 10¹⁵ s⁻¹
ΔP = (5.6 mev) x (6.3 x 10¹⁵ s⁻¹)
ΔP = (5.6 x 10³ x 1.6 x 10⁻¹⁹ J) x (6.3 x 10¹⁵ s⁻¹)
ΔP = 5.65 J/s

Answer:
Option d) can not be determined from the given information
Explanation:
Water is a polar molecule consisting of 2 positive hydrogen atoms and a negative oxygen atom.
When a stream of water is deflected by positively charged object, the water molecules are oriented in such a way that oxygen in water, being negatively charge gets attracted to the charged object and aligns near the object whereas hydrogen aligns on the opposite side overcoming the inter-atomic repulsion.
Similar is the case with hydrogen in case the object is negatively charged.
Therefore, it explains that water is a polar molecule and gets attracted to both positive and negative charges and hence, the sign of the object can not be determined.
In order to find the speed per minute you will have to divide the two numbers together. You need to do 36/5.4 so the answer will be around 6.7 feet per minute.
Answer:
Using 3 periods to get an accurate reading:
3T = (6.40 S - 0.90 s) = 5.50 S So, T = 1.83 s
m = 0.250 kg
Using algebra:
k= 
=
=2.95kg/sec
