According to our principle, when an object is slowing down, the acceleration is in the opposite direction as the velocity. Thus, this object has a negative acceleration.An object with negative acceleration could be speeding up, and an object with positive acceleration could be slowing down.
Since
Force (weight) = mass x acceleration (gravity)
To determine acceleration, the formula will be:
Acceleration = Force / mass
Given are:
F = 10 N
M = 2kg
A = ?
Solution:
1. A = F/M
2. A = 10 kg*m/s2 / 2kg
3. A = 5 m/s2
Answer:
double
Explanation:
radius = r
length = l
Surface area, A = 2 π r l .... (1)
Now the radius is doubled = 2r
length is same
Surface area, A' = 2 x π x 2 r x l
A' = 2 x 2πrl
A' = 2 A (from equation (1)
Thus, the surface area is doubled.
Answer:
Raindrops start to form in a roughly spherical structure due to the surface tension of water. This surface tension is the "skin" of a body of water that makes the molecules stick together. The cause is the weak hydrogen bonds that occur between water molecules.
