Answer:
0.146 m
Explanation:
f = -KΔL according to Hooke's law
volume of water displaced = mass / density of block since a body will displace equal volume of its own
weight of water displaced = mass of water × acceleration due to gravity
and mass of water = volume of water / density of water
weight of water displaced = Vw × dw × g = mg (dw / dblock)
net force = mg - mg (dw / dblock) = 42.728 - 65.74 = -23.00
it will be balanced by a restoring force of 23 N
ΔL = F / k = 23 / 158 = 0.146 m
2) they add the insulation to better the durability or the earbuds
False i just took the test and put true as a guess but got it wrong so it is false
please give me a brainlies
I think the correct answer from the choices would be that metals donate electrons to nonmetals. Ionic bonding involves transfer of valence electrons. The metal looses its valence electrons which makes it a cation while the nonmetal accepts these electrons.
The time the truck must apply the given force to increase its speed to given value is 5 s.
The given parameters;
- <em>applied force, F = 600 N</em>
- <em>mass of the truck, m = 1,500 kg</em>
- <em>speed of the truck, v = 2 m/s</em>
The force applied to the truck is determined by Newton's second law of motion; <em>which states that the force applied to an object is directly proportional to the product of mass and acceleration of the object.</em>
F = ma

Thus, the time the truck must apply the given force to increase its speed to given value is 5 s.
