Answer 1

Here are the answers to your questions:

**23. The force of gravity pulls the moon and Earth toward each other.**
A) True

**24. Mark weighs 200 Newtons on Earth, where the force of gravity is 10 m/s². He goes to Mars, where the force of gravity is 3.5 m/s². What is Mark's weight on Mars?**
To calculate weight, we use the formula:
Weight = mass × gravitational acceleration

First, we need to find Mark's mass. Using his weight on Earth:
Weight on Earth = mass × gravitational acceleration (Earth)
200 N = mass × 10 m/s²
mass = 200 N / 10 m/s² = 20 kg

Now we can find his weight on Mars:
Weight on Mars = mass × gravitational acceleration (Mars)
Weight on Mars = 20 kg × 3.5 m/s² = 70 N

So, the answer is:
**d) 70 N**

**25. Which statement about gravitational attraction is correct?**
a) All objects with mass experience gravitational attraction.

**26. What increases as gravitational force increases?**
b) weight
