Increasing its velocity will add to the kinetic energy more as the formula for kinetic energy is 0.5*m*v^2. (The speed will be squared making it greater)
Answer:
1600 kg
Explanation:
use the formula p=mv. p=3200, v=2. Plug in and rearrange.
3200=(m)(2)
m= 3200/2
m=1600
Around 70-72% of earth’s surface is covered in water (most of it is salt water).
Hope this helps.
Answer:
Na3P + <u>3</u>RbF -> <u>3</u>NaF + Rb3P
Answer:
4.6091 meters
Explanation:
In this problem, to have equilibrium in the seesaw, we need the torque from one child to compensate the torque from the other child.
The torque is calculated by making the product of the mass and the distance to the pivot point.
So, the torque generated by the first child (T1) is equal to:
T1 = m1 * d1 = 39 * 2.6 = 101.4 Nm
To make equilibrium, we need the second child to generate the same torque (T2), so:
T2 = m2 * d2 = 22 * d2 = 101.4
d2 = 101.4 / 22 = 4.6091 m
The second child need to be at 4.6091 meters from the pivot point to be in equilibrium.
