Pounds
If you are talking about the unit of measurement for weight is that of force it would be Newtons.
Answer:
Ethan's tangential speed is twice as Rebecca's.
Explanation:
Let 
be the distance from the center of the platform to Rebecca's horse, 
Rebecca's tangential speed, 
the Ethan's tangential speed and 
the merry-go-round angular speed. The distance from the center of the platform to Ethan's horse is 
. The angular speed is related to the tangential speed by the equation:
Since the angular speed is the same for Ethan and Rebecca, we have that:
Now, solving for we get:
It means that Ethan's tangential speed is twice as Rebecca's.
Answer:
Explanation:
given.
Two flat 4.0 cm × 4.0 cm electrodes carrying equal charge
space between the charges = 2 mm
Electric field strength = 7.6 x 10⁶ N/C
ε ₀ = 8.85 × 10⁻¹² C²/N · m²
magnitude of charge =?
Electric field strength between to two plates
There is no image??? i think you forgot it attach it
Density offers a convenient means of obtaining the mass of a body from its volume or vice versa; the mass is equal to the volume multiplied by the density (M = Vd), while the volume is equal to the mass divided by the density (V = M/d).
M = V d
M = 1.4 * 2 = 2.8 kg
