Answer:
Mass of object (m) = 5.102 kg
Explanation:
Given:
Horizontal Force (F) = 50 N
Find:
Mass of object (m) = ?
Computation:
We know that, acceleration due to gravity (g) = 9.8 m/s²
⇒ Horizontal Force (F) = mg
⇒ 50 N = m (9.8 m/s²)
⇒ Mass of object (m) = 50 / 9.8
⇒ Mass of object (m) = 5.102 kg
Mass of object (m) is 5.1 kg (Approx)
Answer:
An acute injury is sudden and severe such as a broken bone. A chronic injury develops and worsens over an extended period of time like shin splints
Explanation:
i’m pretty sure it’s , the alkali metals
Look at the title of the graph, in small print under it.
Each point is "compared to 1950-1980 baseline". So the set of data for those years is being compared to itself. No wonder it matches up pretty close !
Answer:
q = 3.6 10⁵ C
Explanation:
To solve this exercise, let's use one of the consequences of Gauss's law, that all the charge on a body can be considered at its center, therefore we calculate the electric field on the surface of a sphere with the radius of the Earth
r = 6 , 37 106 m
E = k q / r²
q = E r² / k
q =
q = 4.5 10⁵ C
Now let's calculate the charge on the planet with E = 222 N / c and radius
r = 0.6 r_ Earth
r = 0.6 6.37 10⁶ = 3.822 10⁶ m
E = k q / r²
q = E r² / k
q =
q = 3.6 10⁵ C
