Answer:
17.46° W of N
Explanation:
His prow must point westward so that the westward component of his total velocity is equal to the eastward river speed.
3 = 10sinθ
sinθ = 3/10
θ = 17.4576... or about 17.46° W of N
it will take him 5 / 10cos17.46 = 0.52414... hrs. or about 31 min 27 s to cross.
Answer:
20 ohms,100*2/10=20
Explanation:
since it as to be in parallel arrangement and connected in side by side due to same p.d in a cross each resistor
Answer: Aerial plants is plants that lives in air or wind the wind serves as the water of the plants. Most aerial plants are found in tropical and equatorial regions of the world. In evergreen rain forests, the foliage is so thick that some plants have evolved aerial roots to allow them to absorb more sunlight. The development of aerial roots is
thus an evolutionary process.Aerial roots are often thick and spread around the parent tree. The Banyan tree can have several aerial roots as it gets older.
Explanation:
Scientists need a standard system of measurement to allow for consistency with measurement data (A). Scientists would not be able to understand what other scientists are saying if everyone uses their own system of measurement. Scientists need to take measurements, interpret them and communicate the results to other scientists. That is why a standardized system of taking measurements has been developed. The International System of Units or the Metric system is the measurement system of choice for scientists all over the world today.
