Answer:
According to Newton's Second Law of Motion :
Where,
F = Force Applied
m = Mass of the object
a = Acceleration
Now, we will use this law to solve this question.
Given :
Acceleration or a = 15.3 m/s²
Force = 44 N
Mass = ?
Substitute, the given values in the formula.
F = ma
⇒ m = F/a
m = 44/15.3
<u>m = 2.9 kg</u>
Answer:
1.25 focal lengths
Explanation:
The lens equation states that:
where
f is the focal length
p is the object distance
q is the image distance
In this problem, the image is 4 times as far from the lens as is the object: this means that
If we substitute this into the lens equation and we rearrange it, we get
so, the object distance measured in focal lengths is
1.25 focal lenghts
Sublimation = A process in which solid substance directly changes in has and vice versa.

If the it took the object travelling at 25m/s 1 second to travel a quarter of the circle, it means a quarter of the circle is 25m (it travels 25m in one second).
If the quarter of the circle is 25m than the circumference of the circle is 100m.
We want to calculate the radius of the circle.
Remember that the equation for finding the circumference contains the radius. We can use that equation to solve for the radius.
Circumference = 2πr
π = pi or 3.1415...... ( a number )
r = radius
Since we know the circumference, plug it in.
100m = 2πr
solve for the radius by isolating r.
100m/2π = r
r = radius = 100m/2π = 50m/π = 50/π meters

Answer: Radius = 50/π meters</h2>
