Answer: (a) The magnitude of its temperature change in degrees Celsius is 15.1^{o}C.

(b) The magnitude of the temperature change (change in T = 15.1 K) in degrees Fahrenheit is 27.2^{o}F.

Explanation:

(a)  Expression for change in temperature is as follows.

        |\Delta T| = |x - y|K

                         = 15.1 K

                    = |(x - 273.15) - (y - 273.15)|^{o}C

                    = |x - y|^{o}C

                    = 15.1^{o}C

Therefore, the magnitude of its temperature change in degrees Celsius is 15.1^{o}C.

(b)  Change in temperature from Celsius to Fahrenheit is as follows.

           F = 1.8C + 32

          C = \frac{F - 32}{1.8}

Since,   K = C + 273

or,    \Delta K = \Delta C = \frac{\Delta F}{1.8}

         \Delta F = 1.8 \Delta K

                      = 1.8 (15.1)

                      = 27.18^{o}F

or,                  = 27.2^{o}F

Thus, we can conclude that the magnitude of the temperature change (change in T = 15.1 K) in degrees Fahrenheit is 27.2^{o}F.

Answer:

a.15.1 degree Celsius

b.27.18 degree Fahrenheit

Explanation:

We are given that

Temperature,\Delta T=15.1 K

a.We have to find the magnitude of its temperature change in degree Celsius.

Let initial temperature=x K

Final temperature=y K

\Delta T=y-x=15.1 K

^{\circ} C=K-273

Using the formula

\mid\Delta T\mid=\mid{(x-273)-(y-273)}\mid

\mid\Delta T\mid=\mid y-x\mid=15.1^{\circ} C

b.^{\circ}F=1.8^{\circ}C+32

1.8^{\circ} C=^{\circ}F-32

^{\circ} C=\frac{^{\circ}F-32}{1.8}=\frac{^{\circ}F}{1.8}-17.8

\Delta ^{\circ}C=\frac{\Delta ^{\circ}F}{1.8}

K=^{\circ}C+273

\Delta K=\Delta ^{\circ}C=\frac{\Delta ^{\circ}F}{1.8}

\Delta ^{\circ}F=1.8\Delta K=1.8\times 15.1=27.18^{\circ} F

A baseball player throws a ball borontally, which of the following statements best
MariettaO [177]

Answer:

Its vertical speed increases, and its horizontal speed remains the same.

Explanation:

Given that,

A baseball player throws a ball horizontally,

We know that,

A baseball player throws a ball horizontally, then vertical component of gravity will be increases but there is no acceleration in horizontal direction

So, horizontal velocity remains same.

Hence, Its vertical speed increases, and its horizontal speed remains the same.
