Answer: at the equator the normal force will be 3.4N less and at the North Pole = 980N
Explanation:
So, we will start the Calculation by considering the equation below;
Fnet = F(g) - F(N); where Fnet = mv^2/ r.
Hence, F(g) - F(N) = mv^2/ r -------------(1).
Making F(N) the subject of the formula, we have;
F(N) = Gm1m2/r^2 - mv^2/r.
Thus, we have;
Gm1m2/r^2 = 6.68 × 10^-11 × (5.98 × 20^24) × 100/ 6.38 × 10^6 = 980N.
Also, we have;
mv^2/r = m4π^2r/T^2.
100 × 6.38 ×10^6 × 4π^2/(24 × 3600)^2 = 3.4N
Therefore, at the equator the normal force will be 3.4N less and at the North Pole = 980N.
Answer:
The differences between Karakum and Kyzylkum Deserts are:
1. Karakum means Black Sand because of the black soil that is beneath the sandy desert while Kyzylkum means Red Sand.
2. Karakum has an irrigation system that sustains the farming of most part of Turkmenistan while Kyzylkum is located between two rivers and is shared by three countries, Kazakhstan, Uzbekistan, and Turkmenistan.
The Karakum Desert is a desert in Central Asia.ts name suggests that Black Sand in Turkic languages, in respect to the dark soil that lies at a lower place the sandy surface of abundant of the desert. It occupies concerning seventy %, or 350,000 km², of the realm of country.
The Kyzylkum Desert is in central Asia and its name suggests that Red Sand in Turkic languages. It covers concerning 298,000 km2.D desert fauna embody the Russian turtle.
Answer:
The EMF of the batteries connect in series in the circuit is 12 V.
Explanation:
Given;
two batteries, each is 6 V
The EMF of the batteries connect in series in the circuit is calculated as sum of the voltage of the two batteries since they are connected in series.
EMF = V₁ + V₂
EMF = 6V + 6V
EMF = 12 V
Therefore, the EMF of the batteries connect in series in the circuit is 12 V.
