Answer:
91 m
Explanation:
v₀ = 2.5 m/s
a = 4.2 m/s²
t = 6.0 s
Find: Δx
Δx = v₀ t + ½ at²
Δx = (2.5 m/s) (6.0 s) + ½ (4.2 m/s²) (6.0 s)²
Δx = 90.6 m
Rounded to the nearest whole number, the distance traveled is 91 m.
Work or energy spent=force times distance=25N*4m=100Nm
power=energy or work divided by time=100Nm/5s=20Nm/s
Answer:
The water from the surface of the Earth must be evaporated by the sun.
Explanation:
Answer:
The magnitude of the electrostatic force is 120.85 N
Explanation:
We can use Coulomb's law to find the electrostatic force between the down quarks.
In scalar form, Coulomb's law states that for charges 
and 
separated by a distance d, the magnitude of the electrostatic force F between them is:
where 
is Coulomb's constant.
Taking the values:
and knowing the value of the Coulomb's constant:
Taking all this in consideration:
As the air becomes warmer, heat<span> is transferred </span>between<span> molecules and kinetic</span>energy<span> is created which produces </span>thermal energy<span>. As the molecules move faster to transfer </span>heat<span>, the </span>temperature<span> also increases.</span>
