The amount of force needed by the truck to move the boulder is 200 N.
<h3>Force:</h3>
This can be defined as the product of mass and acceleration. The S.I unit of force is Newton or kgm/s²
To calculate the newton's of force a block needs to move, we use the formula below.
Formula:
- W = Fd............. Equation 1
Where:
- W = Work done by the truck
- F = Force applied on the boulder
- d = Distance moved by the boulder
Make F the subject of the equation
- F = W/d................. Equation 2
From the question,
Given:
Substitute these values into equation 2
Hence, the amount of force needed by the truck to move the boulder is 200 N.

Answer:
i did not learn this yet im going into 6th grade im still in 5th
i dont know
Answer:
17.71N/m
Explanation:
The period of the spring is expressed according to the expression;

m is the mass of the object
k is the force constant
Given
m = 5.50kg
T = 3.50s
Substitute into the formula;

Hence the force constant of the spring is 17.71N/m
The question isn't clear enough, I think it ask us to calculate the linear speed of a point at the edge of the DVD.
Now let's imagine we're a point at the edge of the DVD, we're undergoing a circular motion. Each minute we will complete a circular track 7200 times, now we need to know the distance we travel each turn. The perimeter of the DVD, a circular object is:

Know recall that:

We now need to know how much distance is traveled during a minute or 60 seconds:

Finally we divide this result with t=60 seconds:


Where the distance units were named units as the length unit is not specified in this exercise.<span />
Answer:
gamma ray, or gamma radiation (symbol γ or {\displaystyle \gamma } \gamma ), is a penetrating form of electromagnetic radiation arising from the radioactive decay of atomic nuclei. It consists of the shortest wavelength electromagnetic waves and so imparts the highest photon energy. Paul Villard, a French chemist and physicist, discovered gamma radiation in 1900 while studying radiation emitted by radium. In 1903, Ernest Rutherford named this radiation gamma rays based on their relatively strong penetration of matter; in 1900 he had already named two less penetrating types of decay radiation (discovered by Henri Becquerel) alpha rays and beta rays in ascending order of penetrating power.
