Frame of reference, in simplest terms, describes the state of motion of the observer. The frame of reference may also be described by using a set of coordinates, time and motion. We formulate all our equations and solve them using the frame of reference.
Answer:
Water temperatures are slow to heat up, It takes 4 times the energy to heat up water than to heat air. Water also "feels" colder because water is a more efficent medium than air to cool our body down.
Re word it tho
Hope this helps!!
Answer:
13.18m/s²
Explanation:
According to Newton's second law of motion
Force = Mass * acceleration
Given
Mass = 11kg
Force = 145N
Required
acceleration
From the formula
Acceleration = Force/Mass
Acceleration = 145/11
Acceleration = 13.18m/s²
Hence the initial acceleration of the object is 13.18m/s²
Answer:
Explanation:
108,000 beats per hour
613,200 hours in 70 years
108,000 times 613,200 =
66225600000 beats
Answer:
on the planet
on earth
Explanation:
Given:
- initial velocity of the tool before pushing,
- force applied on the tool,
- displacement of the tool,
- time taken for the displacement,
- height of releasing the tool,
- time taken by the tool to fall on the ground,
<u>Now using the equation of motion:</u>
where:
a = acceleration of the object
Now the mass of the tool:
<u>Using the equation of motion when the tool is dropped:</u>
here:
g = acceleration due to gravity on the planet
Weight of the tool in the planet:
Weight of the tool on the earth:
