Emmit is lifting a box vertically which forces are necessary for calculating the total force

Physics
1 answer:
zavuch27 [327]3 years ago
4 0

Answer:

FG and FP

Explanation:

Gravitational Force(FG) because the box is being pulled down and a resistance force pushing up because he is pushing(FP) up on the box.

I hope this helps!

Using the diagram shown, what is the magnitude of the resultant of these three forces?
amid [387]

Explanation:

The x component of the resultant force is the sum of the x components of the individual forces.

Fₓ = 65.0 cos 30° − 20.0 sin 20° − 30.0

Fₓ = 19.5

The y component of the resultant force is the sum of the y components of the individual forces.

Fᵧ = 65.0 sin 30° − 20.0 cos 20°

Fᵧ = 13.7

The magnitude is found with Pythagorean theorem:

F² = Fₓ² + Fᵧ²

F² = (19.5)² + (13.7)²

F = 23.8

A series circuit contains a 100.0-Ω resistor, a 0.450-H inductor, a 0.360-µF capacitor, and a time-varying source of emf providi
eduard

Answer:

A) The resonance angular frequency in an L-R-C circuit is

\omega_0 = \frac{1}{\sqrt{LC}} = \frac{1}{\sqrt{0.45\times0.36\times 10^{-6}}}\\\omega_0 = 2.48\times10^3 rad/s

B) The current can be found by calculating the impedance of the system.

Z = \sqrt{R^2 + (X_L - X_C)^2} = R

Since X_L = X_C at resonance.

So, I = V/Z = V/R = 30 / 100 = 0.3A

Which example is a body fossil? a) dino bones b) shrimp burrow c)dino footprint d)an ornithopod track
Harrizon [31]

Answer:

The hard structure like dino bones, teeth and shells are the examples of body fossils.

Option: A

<u>Explanation: </u>

The body fossils are common type of fossils found in the world. <em>These body fossils are formed by the remains of the ‘dead animals and plants’.</em> The body fossils are <em>hard parts of the dino teeth, bones, shells, woody trunks, branches, and stems.</em> The body fossils are formed in different ways and they are the remains of <em>the body parts of ancient animals, plants and other life forms.</em>

<em>They are rarely found in connected nature and are like large vertebrates like dinosaur bones, skulls and teeth’s. </em> The body fossils are also formed in different ways they are formed like a plants or animals dies in a watery environment and they can be buried in mud or silt they cannot decompose.

They build the top and hardens into the rocks at over time sedimentation.  Two types of tissues are decomposed, they are soft and hard tissues.in the decomposition of there leaving hard bones, shells and teeth’s are behind and soft tissues are quickly decomposes.
