Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions here.
Below are the choices that can be found from other sources:
A. The marlin has more momentum.
<span>B. The salmon has more momentum. </span>
<span>C. Both have the same momentum. </span>
<span>D. Both have no momentum.
</span>
Velocity is speed. Momentum is the product of velocity and mass. Because the Marlin has a much greater mass that means that it's momentum would also be greater.
<span>Lets look at this. momentum = mass x velocity </span>
<span>lets say that velocity for both fish is at 2 meters per second </span>
<span>Marlin : momentum = 500 x 2 = 1000 </span>
<span>Salmon : momentum = 20 x 2 = 40 </span>
<span>Therefore the answer is A</span>
1) Acceleration of the sled
The acceleration of the sled is given by the net force acting in the direction parallel to the incline. There are two forces acting along this direction: the component of the weight parallel to the ramp (downward) and the friction (upward). Therefore, the net force acting in this direction is
And the acceleration is given by Newton's second law:
2) Normal force
The normal force acting on the sled is equal to the component of the weight perpendicular to the incline, therefore:
Answer:
The correct option is the last option.
Explanation:
Generally, when trying to create a mechanical advantage of a lever for an apparatus or a machine, <u>the load is usually moved closer to the fulcrum</u>. Hence, if a lever has a total length of 12 meters and the fulcrum is placed at 6 meters (the center), the best way (based on the previous statement) to double the mechanical advantage of the lever is <u>to move the fulcrum 4 meters toward the side on which the force is applied</u>. The correct option is the last option.
Answer:
Explanation:
Density can be found by dividing the mass by the volume.
The mass is 5.28 grams and the volume is 2 cubic centimeters.
Substitute the values into the formula.
Divide.
The density of the unknown substance is 2.64 grams per cubic centimeter.
The density of a diamond is about 3.5 grams per cubic centimeter. Since 2.64 is not equal to 3.5, the unknown substance is not a diamond.
