Accelerated motion is represented by a _____ line on a nonlinear distance-time graph.

Physics

Natasha_Volkova [10]3 years ago

Accelerated motion could be changing speed, or changing direction, or both.

If it's only the direction changing and not the speed, then you'll never see it on a distance/time graph.

If the speed is changing, then a <em>velocity</em>/time graph can be any kind of a line except horizontal or vertical, and a <u><em>distance</em></u>/time graph must be <em>curved</em>.

Answer:

Accelerated motion is represented by a <u>CURVED</u> line on a nonlinear distance-time graph.

Explanation:

For uniform acceleration we know that

\frac{dv}{dt} = a

now integrating both sides we will have

\int dv = \int adt

now after integration we will have

v - v_o = at

now we have

v = v_o + at

again we know that

\frac{dx}{dt} = v_o + at

again by integration both sides

x - x_0 = v_o t + \frac{1}{2}at^2

x = x_0 + v_0t + \frac{1}{2}at^2

now since this equation is a quadratic equation so here distance time graph must be a curved graph

Uranus and neptune have methane clouds but jupiter and saturn do not. Which factor explains why?.
mr Goodwill [35]

Answer:

Temperature on Jupiter and Saturn are too high for methane to condense.

Explanation:

However, methane can condense on Uranus and Neptune because they are farther from the sun and hence colder.

Two balloons (m = 0.021 kg) are separated by a distance of d = 16 m. They are released from rest and observed to have an instant
evablogger [386]

(a) 2.56\cdot 10^{-5} C

According to Newton's second law, the force experienced by each balloon is given by:

F = ma

where

m = 0.021 kg is the mass

a = 1.1 m/s^2 is the acceleration

Substituting, we found:

F=(0.021)(1.1)=0.0231 N

The electrostatic force between the two balloons can be also written as

F=k\frac{Q^2}{r^2}

where

k is the Coulomb's constant

Q is the charge on each balloon

r = 16 m is their separation

Since we know the value of F, we can find Q, the magnitude of the charge on each balloon:

Q=\sqrt{\frac{Fr^2}{k}}=\sqrt{\frac{(0.0231)(16)^2}{9\cdot 10^9}}=2.56\cdot 10^{-5} C

(b) 1.6\cdot 10^{14} electrons

The magnitude of the charge of one electron is

e=1.6\cdot 10^{-19}C

While the magnitude of the charge on one balloon is

Q=2.56\cdot 10^{-5} C

This charge can be written as

Q=Ne

where N is the number of electrons that are responsible for this charge. Solving for N, we find:

N=\frac{Q}{e}=\frac{2.56\cdot 10^{-5}}{1.6\cdot 10^{-19}}=1.6\cdot 10^{14}
