Answer:

Option B: the period during which a solid is not changing state; its temperature is increasing

Explanation:

The temperature is defined as a measurement of the speed at which particles of matter are moving (their kinetic energy)

Therefore for an increase of kinetic energy to take place, and increase of temperature has to occur.

The slowest moving animal is a crab found in the Red Sea. It travels with an average speed of 5.7 Km/year How long will it take

Anastasy [175]

Time = distance / speed

Time = (100 km) / (5.7 km/yr)

<em>Time = 17.5 years</em>

If this is true, then it's not likely that any member of the species has ever traveled 100 km in its lifetime. Weird !

How do you know whether to put a nine or a 10 in front of the number on the weather station

3241004551 [841]

If the air pressure on the station model is 500 or more, place a 9 in front of this number. If the pressure number on the station is less than 500 add a 10 in front of this number.

Good luck :)

Answer: 26.67 m/s

Explanation:

Given

Length traveled by the ball $s=40\ m$

Time taken to reach the goal post is $t=3\ s$

Initial velocity $u=0\ m/s$

Using the second equation of motion

$\Rightarrow s=ut+\frac{1}{2}at^2\\\Rightarrow 40=0+\frac{1}{2}a(3)^2\\\Rightarrow a=\frac{80}{9}\ m/s^2\\$

Now using

$\Rightarrow v^2-u^2=2as\\\\\Rightarrow v^2-0=2\times \frac{80}{9}\times 40\\\\\Rightarrow v=\sqrt{\dfrac{80\times 80}{9}}=\dfrac{80}{3}\\\Rightarrow v=26.67\ m/s$

The velocity of ball will be 26.67 m/s
