Answer:

<h2>False.</h2>

Explanation:

A fossil fuel is a fuel formed by natural processes. Fossil fuels typically have an age of millions of years, and sometimes more than 650 million years. It cannot process to create fossil fuel again.

<h3>Further Explanation:</h3><h3 />

A nonrenewable resource is a natural substance that is not replenished with the speed at which it is consumed. It is a finite resource.

Nonrenewable resources come from the Earth. Humans extract them in gas, liquid, or solid form and then convert them for their use, mainly related to energy. The reserves of these substances took billions of years to form, and it will take billions of years to replace the supplies used.

the weight of an object on earth is 350 newtons. on mars the same object would weigh 134 newtons. what is the acceleration due t

Eddi Din [679]

Mass will remain constant on both planet, let mass of the object be "m".
let x be the acceleration due to gravity on the surface of mars.
Weight of object on earth = m *g , where g is acceleration due to gravity on the surface of earth
⇒350 = m * 9.8
⇒m = 350 / 9.8 .............................equation(1)
Weight of object on mars = m * x , where x is acceleration due to gravity on the surface of mars
134 = m * x .............................equation(2)
putting the value of m from equation (1) in equation(2) , we get,
x = (134 * 9.8) / 350
⇒ x = 3.572 m/s²

Dr. John Paul Stapp was U.S. Air Force officer who studied the effects of extreme deceleration on the human body. On December 10

Mars2501 [29]

Answer:

a) $a=5.7551 \times g$

b) $d=20.5539\times g$

Explanation:

Given:

speed of rocket initially, $v_i=0\ m.s^{-1}$

top speed of rocket after acceleration, $v=282\ m.s^{-1}$

time taken to get to the top speed, $t_i=5\ m.s^{-1}$

final speed of the rocket, $v_f=0\ m.s^{-1}$

time taken to get to the final speed after reaching the top speed, $t_f=1.4\ s$

Now the acceleration:

$a=\frac{v-v_i}{t_i}$

$a=\frac{282-0}{5}$

$a=56.4\ m.s^{-2}$

Now as a fraction of gravity:

$a=\frac{56.4}{9.8}\times g$

$a=5.7551 \times g$

Now, the deceleration:

$d=\frac{0-282}{1.4}$

$d=201.4285\ m.s^{-2}$

Now as a fraction of gravity:

$d=\frac{201.4285}{9.8}\times g$

$d=20.5539\times g$

The dielectric strength of rutile is 6.0 × 106 V/m, which corresponds to the maximum electric field that the dielectric can sust

VLD [36.1K]

Answer:

6.48*10⁻⁷ C

Explanation:

By definition, the capacitance of a capacitor is expressed as follows:

$C =\frac{Q}{V}$

where Q is the charge on one of the plates of the capacitor, and V the potential difference between the plates.
The maximum electric field, the potential difference, and the distance between plates are related by the following expression:

$V = E_{max} * d$

Replacing by the givens, we can find V as follows:

$V = 6.0e6 V/m * 0.00108 m= 6480 V$

Now, we can find the maximum charge Qmax, as follows:

$Q_{max} = C*V = 1e-10F* 6480 V = 6.48e-7 C$

The maximum charge that the capacitor can hold is 6.48*10⁻⁷ C.
