Explanation:

According the Newton's second law of motion, force applied on an object is directly proportional to its mass and acceleration.

Mathematically, the relation is as follows.

Force = mass × acceleration

or, Acceleration = $\frac{Force}{mass}$

Thus, we can conclude that according to Newton’s second law of motion, the acceleration of an object is inversely proportional to the mass of object.

Answer:

$\mathbf{f_o =1.87 \times 10^{11} \ Hz}$

Explanation:

From the given information:

The elastic potential energy can be calculated by using the formula:

$U_o = \dfrac{1}{2}kR_o^2$

Making K the subject;

$K = \dfrac{2 U_o}{R_o^2}$

$k = \dfrac{2\times 1.68 \times 10^{-21}}{(3.82\times 10^{-10})^2}$

k = 2.3 × 10⁻² N/m

Now; the frequency of the small oscillation can be determined by using the formula:

$f_o = \dfrac{1}{2 \pi}\sqrt{\dfrac{k}{m}}$

where;

m = mass of each atom = 1.66 × 10⁻²⁶ kg

$f_o = \dfrac{1}{2 \pi}\sqrt{\dfrac{2.3 \times 10^{-2} N/m}{1.66 \times 10^{-26} \ kg}}$

$\mathbf{f_o =1.87 \times 10^{11} \ Hz}$

A skier is traveling fast down a mountain slope. The table shows data

melisa1 [442]

Answer:

The pushing force and the skier's mass

(A) is correct option.

Explanation:

Given that,

Mass = 64 kg

Weight = 608 N

Velocity = 21 m/s

Forward force = 45 N

We need to calculate the reaction force of the snow pushing on the skier

Using given data,

The reaction force of the snow pushing on the skier is equal to the pushing force and the skier's mass.

Hence, The pushing force and the skier's mass

(A) is correct option.

Answer:

Explanation:

a ) Kinetic energy of ball = 1/2 m v² , m is mass of the ball and v is its velocity

= 1/2 x .058 x 80²

= 185.6 J .

b ) The velocity of ball is very high so we shall find out the relativistic kinetic energy , the formula is given below

kinetic energy = mc² ( $\frac{1}{\sqrt{1-\frac{v^2}{c^2} } } -1$ )

= mc² x $\frac{1}{\sqrt{1-\frac{v^2}{c^2} } }$ - mc²

= .058 x 9 x 10¹⁶ x $\frac{1}{\sqrt{1-\frac{1.8^2}{3^2} } }$ - .058 x 9 x 10¹⁶

= .058 x 9 x 10¹⁶ x 1 / .8 - .058 x 9 x 10¹⁶

.058 x 9 x 10¹⁶ ( 1.25 - 1 )

= .058 x 9 x 10¹⁶ x .25

= .1305 x 10¹⁶

= 13.05 x 10¹⁴ J .
