GM foods should be labeled in food stores. If, for example, someone wanted to buy a GM Apple, which could be enriched in chemicals, that should be labeled different than a regular apple. What if someone was allergic to some of the modifications in that apple. If there was a label on that apple, that person would not get a allergic reaction. That is why GM products should be labeled.

Force required = F = ?
mass of the car = m = 1200 kg
initial velocity of the car = Vi = 10 m/sec
final velocity of the car = 0
time required to stop the car = t = 20 sec
Using Newton`s 2nd law of motion;
F = ma ………………………(1)
as a = Vf - Vi / t , put this value in equation (1)
F = m ( Vf - Vi /t ) ………………(2)
F = 1200 ( 0 - 10 /20) = - 600 N
here Negative sign shows that external force is acting in opposite direction of the motion to bring it to rest.
we can also calculate this force by using the relation
Rate of change of momentum = net force acting on the object …………(3)
m Vf - m Vi / t = net force acting on the object
m (Vf - Vi / t) = F
1200 ( 0 - 10 /20) = - 600 N = F
so, net force acting on the object =F = - 600 N
This because ice is less dense than water of particular temperature range. Water reaches its maximum density at 4 degrees. Ice is important especially for aquatic life in the polar regions. Polar bears give birth and hunt on sea ice and they need it to travel from one region to another. The ice edge in coastal areas is an important feeding ground for the walrus that uses the ice as diving platforms to feed on clams on the sea floor. Ice algae grow at the porous bottom of sea ice and form the base of the unique marine food web connected to sea ice
Answer:
There are multiple answers for a strong or weak base
For a strong one, you can put sodium hydroxide
and for a weak one, you can put methylamine
what makes an acid or base weak or strong is if the acid or the base has a high conductivity of electricity
pH is the measurement of hydronium
