The temperature scale used in science is the Kelvin scale. The correct option among all the options given in the question is option "a". This is the standard scale used for measuring in astronomical and thermodynamics fields. The other scales can create complications as different countries use different type of scales.
Answer:
True
Explanation:
Biosphere refer to regions of the earth(sphere) that supports life. It is made up of biotic and abiotic components. Its abiotic components are non-living components that support life and is made up of the lithosphere (the earth crust,mantle) , atmosphere(area of gases and air which is held by gravitational force) and the hydrosphere(all water bodies which includes ocean, sea, lakes, rivers etc).
Answer:
The magnitude and direction of the force between the two charges is 497.66 N in opposite direction.
Explanation:
From the question given above, the following data were obtained:
Charge 1 (q₁) = 1.4×10¯³ C
Charge 2 (q₂) = 9.1×20¯⁴ C
Distance apart (r) = 4.8 m
Force (F) =?
NOTE: Electric constant (K) = 9×10⁹ Nm²/C²
The magnitude of the force between the two charges can be obtained as follow:
F = Kq₁q₂ / r²
F = 9×10⁹ × 1.4×10¯³ × 9.1×20¯⁴ / 4.8²
F = 11466 / 23.04
F = 497.66 N
Thus, the magnitude of the force is 497.66 N.
Since both charges has the same sign (i.e they both positive), the force between them will be a force of repulsion. Hence the force will be in opposite direction.
Answer:
Explanation:
I will assume the equation reads:
v = 8t²î + 5tĵ
The velocity v is the time derivative of the position x.
