What is the velocity of a fly with a mass of approximately 6.85 times 10 to the negative 6 slugs if it has a kinetic energy of 5

vodka [1.7K]

Velocity of the fly: 1318 m/s

Explanation:

The kinetic energy of an object is the energy possessed by the object due to its motion. It can be calculated as

$K=\frac{1}{2}mv^2$

where

m is the mass of the object

v is its speed

For the fly in this problem, we have

$m=6.85\cdot 10^{-6} kg$ is the mass

K = 5.95 J is the kinetic energy

Solving for v, we find its velocity:

$v=\sqrt{\frac{2K}{m}}=\sqrt{\frac{2(5.95)}{(6.85\cdot 10^{-6})}}=1318 m/s$

Two point charges of equal magnitude are 7.3 cm apart. At the midpoint of the line connecting them, their combined electric fiel

Delicious77 [7]

Answer:

q₁ = q₂ = Q = 14.8 pC

Explanation:

Given that

q₁ = q₂ = Q = ?

Distance between charges = r =7.3 cm = 0.073 m

Combined electric field = E₁ + E₂ = E = 50 N/C

Using formula

$E=2\frac{kQ}{r^2}$

Rearranging for Q

$Q= \frac{Er^2}{2k}\\\\Q=\frac{(50)(.005329)}{2\times 9\times 10^9}$

$Q=14.8\times 10^{-12}\, C\\\\Q=14.8\, pC$

If the box is a distance 1.81 m from the rear of the truck when the truck starts, how much time elapses before the box falls off

alexira [117]

If the box is a distance 1.81 m from the rear of the truck when the truck starts, ... Force of Friction = mu_s * Normal Force( M * G) ... The box starts moving! ... Now that the box is moving, the bed of the truck pulls at it with 17.4 ... out how long it will take the box to reach the back of the truck. ... T^2 = 2 * 1.81 / .64

Explain the different methods that can be used to model the motion of an object.

Simora [160]

Answer:

You can describe the motion of an object by its position, speed, direction, and acceleration. An object is moving if its position relative to a fixed point is changing. idk if this helps.
