Answer:
10
Explanation:
F=m.a
(Force= mass.acceleration)
F = 2.5 = 10 N
Answer:
the table is strong enough to hold the metal
Answer:
-100 kg · m/s
Explanation:
We can find the momentum of an object using the formula:
- p = mv
- where p = momentum (kg * m/s), m = mass (kg), v = velocity (m/s), and p and v are vectors
Let's start by converting the mass of the object to kilograms.
Since the left direction is the negative direction, we know that the velocity of the object is -25 m/s.
Using these variables, we can solve for p in the formula.
- p = mv
- p = (4 kg)(-25 m/s)
- p = -100 kg · m/s
The momentum of the object is -100 kg · m/s.
Answer:
upper motor neurons in the premotor cortex
Explanation:
Motor neurons are a type of nervous system cells that are located in the brain and in the spinal cord. They have the function of producing the stimuli that cause the contraction of the different muscle groups of the organism. They are therefore essential for daily activities that require muscle contraction: walking, talking, moving hands and in general all body movements.
The answer is D. They already knew about animals, plants and skin.
