Answer:
the answers the correct one is a 4
Explanation:
The centripetal acceleration is by
a = v² / R
angular and linear velocities are related
v = w R
let's substitute
a = w² R
for initial condition
a₀ = w₀² R
suppose the initial angular velocity is wo, suppose the angular velocity doubles
a = (2w₀)² R
a = 4 (w₀² R)
a = 4 a₀
when reviewing the answers the correct one is a

Explanation:
WIND AND WATER EROSION (B)
<span>Fossils are the preserved remains or traces of animals, plants, and other organisms from the remote past. The totality of fossils, both discovered and undiscovered, and their placement in fossiliferous (fossil-containing) rock formations and sedimentary layers (strata) is known as the fossil record</span>
Answer:
Resistors in series in the circuit must always have the same current
Explanation:
Resistors are said to be connected in series if they are connected one after another.
The total resistance in the circuit with resistors connected in series is equal to the sum of individual resistances.
Individual resistors in series do not get the total source voltage. Total source voltage divide among them.
According to Boyle’s law, For a fixed amount of an ideal gas kept at a fixed temperature, P (pressure) and V (volume) are inversely proportional.
Therefore,
Given , and .
Thus,
