A sky rocket is launched with a force of 10 N and accelerates at 20 m/s squared what is the mass of this skyrocket
tia_tia [17]

Answer: 0.5 kg

Explanation:

Force of launched skyrocket = 10 N

Acceleration of skyrocket = 20 m/s squared (i.e 20m/s^2)

Mass of the skyrocket = ?

Recall that Force is the product of the mass of an object by the acceleration by which it moves.

i.e Force = Mass x Acceleration

10N = Mass x 20m/s^2

Mass = (10N/20m/s^2)

Mass = 0.5 kg

Thus, the mass of this skyrocket is 0.5 kilograms

Which organisms in this food web are carnivores? Select the two correct
LUCKY_DIMON [66]

The two correct options are Poison dart frog and Boa constrictor. Both these organisms are pure carnivores which are also known as pure meat eaters in the food web. Carnivores are organisms in the food chain that only meat-eaters and never take any type of vegetation in their diet.

Explanation:

  • A Poison dart frog purely survives on meat (meat- eater).
  • Long sticky tongues are used to catch their prey such as ants, flies, insects.
  • Since they produce high toxin levels, it has very few predators in the wild.
  • Boa constrictor is also an organism that eats only meat.
  • While they are young they eat prey like rats, squirrels and mice.
  • The type of attack used by a boa constrictor is an ambush attack type. It attacks its preys using the surprise factor.
