My science teacher said that there is no equivalent unit to a newton

There is no single equivalent unit. Nobody needs two different units that both mean exactly the same thing.

1 Newton is the amount of force that accelerates 1 kilogram of mass at the rate of 1 meter per second per second.

So its equivalent unit is (kg-m/sec^2) .

A house is losing heat at a rate of 1600 kJ/h per °C temperature difference between the indoor and the outdoor temperatures. Exp

Setler [38]

Answer:

1600 kJ/h per K, 888.88 kJ/h per °F and 888.88kJ/h per R

Explanation:

We make use of relations between temperature scales with respect to degrees celsius:

$1 K= 1^{\circ}C+273\\1^{\circ}F= (1^{\circ}C*1.8)+32\\1 R= (1^{\circ}C*1.8)+491.67$

This means that a change in one degree celsius is equivalent to a change of one kelvin, while for a degree farenheit and rankine this is equivalent to a change of 1.8 on both scales.

So:

$\frac{Q}{\Delta T(K)}=\frac{Q}{\Delta T(^\circ C)}=1600 \frac{kJ}{h} per K\\\frac{Q}{\Delta T(^\circ F)}=\frac{Q}{\Delta T(^\circ C*1.8)}=888.88 \frac{kJ}{h} per ^\circ F\\\frac{Q}{\Delta T(R)}=\frac{Q}{\Delta T(^\circ C*1.8)}=888.88 \frac{kJ}{h} per R$

(a) Neil A. Armstrong was the first person to walk on the moon. The distance between the earth and the moon is 3.85 x 108 m. Fin

gizmo_the_mogwai [7]

Answer:

a). 1.28333 seconds

b). 186.66 seconds

Explanation:

a). Given :

Distance between the earth and the moon, d = $3.85 \times 10^8$ m

Speed of the radio waves, c = $3 \times 10^8$ m/s

Therefore the time required for the voice of Neil Armstrong to reach the earth via radio waves is given by :

$t=\frac{d}{c}$

$=\frac{3.85 \times 10^8}{3 \times 10^8}$

= 1.28333 seconds

b). Distance between Mars and the earth, d = $5.6 \times 10^{10}$ m

Speed of the radio waves, c = $3 \times 10^8$ m/s

So, the time required for his voice to reach earth is :

$t=\frac{d}{c}$

$=\frac{5.6 \times 10^{10}}{3 \times 10^8}$

= 186.66 seconds

Express 75−−√ in the form ab√.

Nana76 [90]

We can write 75 = 25 x 3
and √75 = √ (25 x 3) = √25 x √3
Now we know that square root of 25 is 5 a 5x5 = 25
so we can express this in the form of 5√3.
