If the force is 3,000 N and the acceleration is 2 m/s/s. The mass of the car is 1,500 grams (or whatever unit of mass or weight is used in the answer- pounds, kilograms e.t.c.).
The temperature of the water and the and the salinity of water
If a problem says the acceleration is some positive value than solve using that value, a negative acceleration is said to be deceleration. E.g. a car decelerating at 10 m/sec can be said to be accelerating at -10 m/sec.
If a problem states decelerates at A, then use -A for acceleration in the classic equations which are for acceleration. If a problem says accelerates at a negative value like -A the use -A as the value for acceleration, it can also be said to be decelerating at A.
<span>example shows that electromagnetic waves can travel without moving through a specific material is
</span>light passing through a vacuum tube
because it shows that there is no medium
so correct option from above is D
hope it helps
<u>To find the mass, with only the weight</u>:
⇒ must consider the relationship between the mass and weight
⇒ (<em>in other words</em>) we must find the equation that has both the
mass and weight
<u>Based on our physics knowledge, we know</u>:
- Weight: 147N
- Gravitational Acceleration: 9.8 m/s²
<u>Now let's plug in the values, and solve</u>:
<u>Answer: 15 kg</u>
Hope that helps!
<em>*as a note, if you use the gravitational acceleration as 10m/s², then the answer would be 14.7 kg</em>
