Answer:
True
Explanation:
The main differences between a physical property and a chemical property are mentioned below:
A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. Physical properties include color, density, hardness, and melting and boiling points.
While A chemical property describes the ability of a substance to undergo a specific chemical change.
The weight of an object is given by:
where m is the mass and g is the gravitational acceleration.
Miguel's mass is the same on every planet (m=60 kg), the only element changing in the formula is g, the value of the gravitational acceleration, which is different for every planet. So by knowing the ratio , where g is the gravitational acceleration on Earth and is the value of the gravitational acceleration on the planet we are studying, we can calculate the ratio , where W is Miguel's weight on Earth (which we know, it is W=132 lbs), and Wx is the weight on the planet we are studying:
- For the Moon, we have
so the weight on the Moon is
- For Neptune, we have
so the weight on Neptune is
- For Mercury, we have
so the weight on Mercury is

Answer:
a=12 m/s²
Explanation:
Newton's second law of motion states that the acceleration of a body is directly proportional to the force applied and takes place in the direction of force.
This can be summarized as: F=ma, where m is the mass of the object on which force F acts. a is the acceleration due to the force applied.
12N= 1kg×a
a=12N/1kg
a=12m/s²
Answer:
0.408 c.
Explanation:
given,
Cruiser travelling speed, v = 0.6 c
Pursuit ship speed,u = 0.81 c
speed of the he cruiser relative to the pursuit ship =?
now,
c is the speed of light
Speed of the cruiser relative to pursuit ship is equal to 0.408 c.
