Samantha is investigating the densities of several liquids. Which action is the result of her creative thinking.

Calculate pressure when f=50N and a=100m^2

andrezito [222]

Answer:

0.5Pa

Explanation:

P = F/a

F = 50N

a = 100m²

P = 50/100

= 1/2 Pa

= 0.5Pa

Find the magnitude of the resultant of forces 6N and 8N acting at 240° to each other

Alexxx [7]

Answer:

magnitude of the resultant of forces is 11.45 N

Explanation:

given data

force F1 = 6N

force F2 = 8N

angle = 240°

solution

we get here resultant force that is express as

F(r) = $\sqrt{F_1^2+F_2^2+2F_1F_2cos\ \theta}$ ..............1

put here value and we get

F(r) = $\sqrt{6^2+8^2+2\times 6\times 8 \times cos240}$

F(r) = 11.45 N

so magnitude of the resultant of forces is 11.45 N

The tire on this drag racer is severely twisted: The force of the road on the tire is quite large(most likely several times the

Andrew [12]

Answer: Speeding Up

Explanation:

Force is proportional to the acceleration of an object. The greater the force, the more acceleration will be produced.

When the force on the tire is equal to the weight of the car, the car is reaching a stability as a result of increase in motion.

But when the force of the load on the tire is quite large(most likely several times the weight of the car) and is directed forward, then, the car is at high speed.

Wegener believed continents moved, but he did not know how. Identify what needed to happen before Wegener's idea about moving co

pochemuha

D. Advances in technology were needed to gather more evidence.

Explanation:

New technologies had to be developed to ascertain Wegener's claims.

The major flaw in Wegener's postulate was that the moving continents lacked a mechanism to drive them into motion.

His theory needed more scientific backing also.

A major leap was made when new technologies used during the second world war was deployed to investigate the ocean floor.
Sequences of magnetic anomalies were unraveled using equipment developed during the second world war
This gave further proof to the idea of continental drift and it expanded the theory into a more broader and inclusive theory of plate tectonics.
