Answer:
20 N
Explanation:
<em>Newton's second Law of motion</em> law states that If there is a external force acting on an object. Then the rate of change of momentum of that object is directly proportional to the force acting on its.
- the net force acting upon the object <em>(F)</em>
- the mass of the object. <em>(m)</em>
- <em>V </em>Final velocity of the object
- U initial velocity of the object
- mV -Final momentum of the object
- mU - Initial momentum of the object
Due to momentum change of that object, momentum change. We can write the equation bellow this,
F = (mV-mU)/t
When m is constant we can write the above expression like this,
F = m (V-U)/t
There for
(V-U)/t = a ( Rate of change of velocity can be denoted as acceleration )
F = m× a
we can state this in mathematically,
a = F/m
in another representation
F = m*a
Net Force = mass*acceleration
= 10 * 2
= 20 N
object is subjected to a negative acceleration due to the friction.
if im not mistaken plant cells go through a stage called photosynthesis meaning the cells can create it's own energy (food) off of water, Co2 and sunlight.
North and south will apply
D. Binary Stars
Well, galaxies are not stars at all rather they are collection of stars, nebulae, globular clusters and stuff like this.
Meteoroids are something entirely different.
Constellations are the pattern of stars.
So, "Binary Stars" is the Right One.
Answer:
Due to suffocation and toxic paint.
Explanation:
The population of hermit crabs has been decreasing because of suffocation and poison. Many crabs actually die slowly from suffocation because their gills require high humidity in order to breathe properly. Hermit crabs are slowly poisoned by tap water in which the toxic substances present in the paint that dissolves their shells that leads to the death of hermit crabs.
