The physical properties of the bowling ball is that it is hard, smooth and very dense.
<h3>What are physical properties?</h3>
Physical properties are those properties which are easily observable and which involve only physical changes in a substance.
A bowling ball is a solid.
The physical properties of bowling ball include:
- density- it has high density
- texture- it is smooth
- hardness - it is hard
Therefore, the physical properties of the bowling ball is that it is hard, smooth and has high density.

That's true. The give-away is "observation ... in the real world". That's what "field reports" are.
The part I'm not so sure about is those "entific findings".
Answer:
C) 50 m/s
Explanation:
With the given information we can calculate the acceleration using the force and mass of the box.
Newton's 2nd Law: F = ma
- 5 N = 1 kg * a
- a = 5 m/s²
List out known variables:
- v₀ = 0 m/s
- a = 5 m/s²
- v = ?
- Δx = 250 m
Looking at the constant acceleration kinematic equations, we see that this one contains all four variables:
Substitute known values into the equation and solve for v.
- v² = (0)² + 2(5)(250)
- v² = 2500
- v = 50 m/s
The final velocity of the box is C) 50 m/s.
Answer:
The answer is C)The force of gravity from Earth acting on the spacecraft decreased because the distance from Earth increased.
Explanation:
Gravity, a force, is dependent on the mass of the object exerting the gravity and the distance of an outside object from that object. The larger the object, the more gravity it will exert on an outside object. This force decreases as you move away from the object, but it will always still exist and never be equal to 0.
