if the time is taken to bring a ball to rest from a certain velocity 'v'. is reduced to half, what will be the change in the val

777dan777 [17]

The answer is C) rate of change of momentum. The answer is not initial or final momentum as the start and end points are not changing. On the other hand, the time it takes for the ball to change velocity is. This change relates to the change of momentum. Hope this helped :))

A pickup truck is being driven down the highway carrying eight 100 gallon fish tank full of water. A hole is punctured in each t

irakobra [83]

Answer:

Explanation:

The velocity of the vehicle would increase because the the tanks (when filled with water) must have exerted a force which would reduce the velocity of the vehicle at a certain pressure on the gas pedal. Note that force equals mass multiplied by acceleration; as the mass decreases, so the force decreases. Thus, when the mass exerted by this tanks (on the vehicle) decrease as a result of the hole punctured in them, the force exerted by the tanks would also decrease causing an increase in velocity of the pick up truck when the same pressure is applied on the gas pedal throughout (before and after the puncture).

The conservation law that applied here is the law of conservation of energy which states that energy can neither be created nor destroyed but can be transformed from one form to another. This is because the energy the vehicle used in carrying the load (the tanks) was transformed to the energy that resulted in increasing it's velocity (no new energy was formed as the pressure on the gas pedal remained the same).

Learning Goal: To understand the distinction between mass and weight and to be able to calculate the weight of an object from it

Nimfa-mama [501]

Answer:

The true statements are: A, D

Explanation:

This interesting problem of the conceptual relationship between mass and weight, the equation for weight is

W = m g

From Newton's second law

W = ma

Where g the acceleration of gravity, this acceleration can vary at several points, for example, in a vertical circumference the acceleration of gravity is always down and the centripetal acceleration continuously changes direction therefore the body weight constantly changes from zero to the maximum value.

The mass instead is always the same and is the resistance (inertia) to the movement of the bodies

Of the aforementioned the peo has the unit mass multiplied by the acceleration

Weight [N] = mass [kg] acceleration [m / s2]

Weight [lb] = mass [slug] acceleration [ft / s2]

Examine the statements

A) 12.0 lb. True pounds are the mass for acceleration. English measurement system

B) 0.34g False. Grams are units of mass,

C) 120 kg. False. The kilograms is a multiple of the grams, which are units of mass

D) 1600 kN True the newton is the unit of weight, the Newton kilo is a multiple

E) 0.34 m False meters are units of length

F) 411 cm False centimeters is a submultiple of the meter that is a unit of length

The true statements are: A, D
