1 answer:

5 0

Force is studied by physics and according to it four fundamental forces are recognized at the quantum level ordered from weakest to strongest are: the gravitational force, the weak nuclear force, the electromagnetic force and the strong nuclear force.

<h3>What is force?</h3>

It is that magnitude that affects a body and is responsible for changes in its state of motion, according to quantum mechanics ordered from weakest to strongest are:

Gravitational force is the force exerted by one mass on the other, being a weak force.

Weak nuclear force is the force responsible for radioactive decay.

Electromagnetic force is the force that affects electrically charged particles and has two directions (attraction-repulsion).

Strong nuclear force is the force that keeps the nuclei of atoms stable, being stronger than the electromagnetic force.

Therefore, we can conclude that four fundamental forces are recognized at the quantum level ordered from weakest to strongest are: the gravitational force, the weak nuclear force, the electromagnetic force and the strong nuclear force.

A comet is in an elliptical orbit around the Sun. Its closest approach to the Sun is a distance of 4.8 1010 m (inside the orbit

creativ13 [48]

Answer:

Explanation:

From the given information:

Distance $d_i = 4.8 \times 10^{10} \ m$

Speed of the comet $V_i = 9.1 \times 10^{4} \ m/s$

At distance $d_2 = 6 \times 10^{12} \ m$

where;

mass of the sun = $1.98 \times 10^{30}$

$G = 6.67 \times 10^{-11}$

To find the speed $V_f$ :

Using the formula:

$E_f = E_i + W \\ \\ where; \ \ W = 0 \ \ \text{since work done by surrounding is zero (0)}$

$E_f = E_i + 0 \\ \\ K_f + U_f = K_i + U_i \\ \\ = \dfrac{1}{2}mV_f^2 + \dfrac{-GMm}{d^2} = \dfrac{1}{2}mV_i^2+ \dfrac{-GMm}{d_i} \\ \\ V_f = \sqrt{V_i^2 + 2 GM \Big [ \dfrac{1}{d_2}- \dfrac{1}{d_i}\Big ]}$

$V_f = \sqrt{(9.1 \times 10^{4})^2 + 2 (6.67\times 10^{-11}) *(1.98 * 10^{30} ) \Big [ \dfrac{1}{6*10^{12}}- \dfrac{1}{4.8*10^{10}}\Big ]}$

$\mathbf{V_f =53.125 \times 10^4 \ m/s}$

Neko [114]

Frequency (f) = 500 hz (SI)
Velocity (V) = 1250 m/s (SI)
Wavelength (Lambda) = ? meters

$v = \lambda \times f$
$1250 = \lambda \times 500 \\ \lambda = 1250 \div 500 \\ \lambda = 2.5 \: meters$
