Is this science because I am suck at it
Answer: Temperature is the average kinetic energy of the molecules (how hot or cold something feels). Heat energy is the energy created y the motion of the molecules in an object. Heat flows from hot body to cold body. Temperature rises when heated and falls down when an object is cooled down.
There are three main scales commonly used in the world today to measure temperature: the Fahrenheit (°F) scale, the Celsius (°C) scale, and the Kelvin (K) scale. Each of these scales uses a different set of divisions based on different reference points, as described in detail below.
Explanation:
Let the total weight of the body be = x
Let the weight of the heart of the mammals be = y
Now the given percentage of 0.5 %, we will convert it into decimal form,
so this is equal to 0.005 in decimal form,
so the linear equation that gives the heart weight in terms of body weight will be,
y = 0.005x
Answer:
Explanation:
Assume that the distance travelled initially is d.
In order to stop the block you need some external force which is friction.
If we use the law of energy conservation:
a)
Looking at the formula you can see that the mass doesn't affect the distance travelled, as lng as the initial velocity is constant (Which indicates that the force must be higher to push the block to the same speed) therefore the distance is the same.
b) If the velocity is doubled, then the distance travelled is multiplied by 4, because the distance deppends on the square of the velocity.
The term that describes the direction closest to the point of origin is Proximal. Dorsal is the directional term for the movement toward the back of the body. Cephalic is the term that describes the movement towards the top of the body. Ventral on the other hand describes the movement toward the front of the body.
