Answer:

The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.

Hello, I wanted an answer from a mathematician. The number 1.04 is closer to the number 1, 2, 1.25 or 1.5.

babymother [125]

Answer:

Explanation:

Of the 4 numbers given, the answer is 1 or A

If you take the absolute value of abs(1 - 1.04) you get 0.04.

(2 - 1.04) = 0.96

1.25 - 1.04 = .21

1.5 - 1.04 = 0.46

The last three are all larger than 0.04

Note: absolute value means the positive difference between 2 numbers (even though it is negative). If it is negative, absolute value makes it positive.

True or false the refraction of a wave is how many wavelengths pass a fixed point each second

Ksenya-84 [330]

False. That description fits the wave's 'frequency'.
It has nothing to do with refraction.

A locomotive accelerates a 25-car train along a level track. Every car has a mass of 7.7 ✕ 104 kg and is subject to a friction f

MaRussiya [10]

To solve the problem it is necessary to apply the concepts related to Force of Friction and Tension between the two bodies.

In this way,

The total mass of the cars would be,

$m_T = 25(7.7*10^4)Kg$

$m_T = 1.925*10^6Kg$

Therefore the friction force at 29Km / h would be,

$f=250v$

$f= 250*29Km/h$

$f = 250*29*(\frac{1000m}{1km})(\frac{1h}{3600s})$

$f = 2013.889N$

In this way the tension exerts between first car and locomotive is,

$T=m_Ta+f$

$T=(1.925*10^6)(0.2)+2013.889$

$T= 3.8701*10^5N$

Therefore the tension in the coupling between the car and the locomotive is $3.87*10^5N$

50 POINTS please someone answer me these questions and only if you know it please

Which requires more energy, making soup or making toast? Explain.

➪ Making toast requires more energy according to my knowledge because soup is liquid and in liquids the particles move freely and allows heat to transfer more quickly in it. Thus, Soup is made quicker and hence requires less energy whereas a toast (piece of bread) is solid and particles are tightly packed thus they need more energy to get cooked.

What are advantages of double glazed windows?

➪ Double glazed windows are air tight and are sealed properly. They cannot be broken easily which makes it more safe. Double glazed windows reduce the amount of moisture on your window panes, as the airtight seal prevents the condensation from building up. And no condensation means the house will be warmer.

When poor people are forced to sleep outdoors in cold weather, they sometimes use newspapers for blankets. What good is this? Why?

➪ They use newspapers because they have very minute holes in it which have air trapped and that trapped air is bad conductor of heat which does not allow the heat of body to flow outside and keeps them warm.

Why are loose fitting clothes more comfortable than the tight fitting clothes in hot climates?

➪ Loose-fitting clothes allow air to pass through and allows the heat of body to flow out which makes us feel cool whereas tight fitting clothes are touched with skin and does not allow the air to pass through the pores. Thus, making loose clothes more comfortable in hot climates.

How does a thermos flask keep food hot?

➪ A thermos flask does not have any pores or holes in the outer surfacs or inner surface which creates a vaccum inside the flask and does not allow heat to escape. Hence, keeping the food hot for very long time.
