Explanation :

Degree Celsius and degree Fahrenheit are two units of measuring temperature.

The correct formula used to convert degrees Celsius to degrees Fahrenheit is :

$^{\circ}F=\frac{9}{5}\times\ ^{\circ}C+32$

Where,

$^0F$ is temperature in Fahrenheit

$^0C$ is temperature in Celsius

Hence, the correct option is (a).

an 80 kg cart goes around the inside of a vertical loop of a roller coaster. the radius of the loop is 5m and the cart moves at

GarryVolchara [31]

Answer:

F= 224 N

Explanation:

Given that

mass ,m = 80 kg

Radius ,r= 5 m

speed at the top v= 8 m/s

The force at the top = F

Now by using the Second law of Newton's

$F+mg=\dfrac{mv^2}{r}$

Now by putting the values

$F+80\times 10 = \dfrac{80\times 8^}{5}$

Take g = 10 m/s²

$F= \dfrac{80\times 8^2}{5}-800$

F= 224 N

Therefore the force exerted by the track at the top position will be 224 N.

Two balls have masses 18 kg and 47 kg. The 18 kg ball has an initial velocity of 76 m/s (to the right) along a line joining the

BigorU [14]

Answer:

The final velocity of 18 kg ball is $V_{2}$ = 42.09 $\frac{m}{sec}$

Explanation:

Mass of first ball $m_{1}$ = 18 kg

Mass of second ball $m_{2}$ = 47 kg

Initial velocity of 18 kg ball $V_{1}$ = 76 $\frac{m}{sec}$

Initial velocity of 47 kg ball = 0

Final velocity of 18 kg ball $V_{2}$ = ??

Final velocity of 18 kg ball is given by the formula

$V_{2}$ = $\frac{2 m_{1} V_{1} }{m_{1} + m_{2} }$

Put all the values in above formula we get

$V_{2}$ = 2 × 18 × $\frac{76}{65}$

$V_{2}$ = 42.09 $\frac{m}{sec}$

Thus, the final velocity of 18 kg ball is $V_{2}$ = 42.09 $\frac{m}{sec}$

snow_lady [41]

To solve this problem we will proceed to define the Period of a stick, then we will define the frequency, which is the inverse of the period. We will compare the change suffered by the new length and replace that value. The Time period of meter stick is

$T = 2\pi\sqrt{ \frac{L}{g}}$
