Which statement accurately describes the ultraviolet catastrophe

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:

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

1) Beth rode the Flying Saucer ride at her favorite amusement park. The ride hung from a rod and swung back and forth while simu

quester [9]

#1

Since Beth rode the Flying saucer ride which is spinning on its axis while axis is moving to and fro as well, so here Beth will experience two motions in this case

(i) Spinning motion

(ii) Rotational motion

Jill and Scott both traveled for 30 min

So time of motion for both is 0.5 h as we know that 1 h = 60 min

Now from the formula of speed we know that

$speed = \frac{distance}{time}$

Speed of Jill

$v_1 = \frac{5}{0.5} = 10 km/h$

speed of Scott

$v_2 = \frac{10}{0.5} = 20 km/h$

so correct answer is

B) Scott had the faster speed since he rode at 20 k/h while Jill only traveled 10 km/h.

#3

Since we know that <em>acceleration is rate of change in velocity</em>

So here we can say that every motion where velocity changes with time then it is an accelerated motion.

Now change in velocity occurs when either the magnitude will change or its direction will change because here velocity is a vector quantity and it will change with magnitude and direction both.

so here due to oval path the direction of velocity will changes at many points and hence it will be an accelerated motion.

so correct answer is

<em>C) James was right since the car changed direction during the race.</em>

Calculate P3 (in W). W (b) Find the total power (in W) supplied by the source. W Compare the total power with the sum of the pow

noname [10]

Answer:

the principle of conservation of energy cannot be violated.

the correct one is: The total power is equal to the sum of the powers dissipated by the resistors.

Explanation:

The power in an electric circuit is given by

P == I V

In a circuit with several components (resistors) the power dissipated is the current by the voltage in each resistance, by the principle of conservation of energy the current in each resistance is the same if the circuit is in series and the current is the same if The circuit is in parallel, but cannot be greater than the current supplied by the power source.

Therefore, the power dissipated by the entire circuit is the sum of the power dissipated by each part, since the principle of conservation of energy cannot be violated.

When reviewing the answers, the correct one is: The total power is equal to the sum of the powers dissipated by the resistors.
