The mass of a body is 25 kg and the value of acceleration due to gravity is 9.8 m/s2. Calculate the weight of the body. (2+2=4)

Answers

Answer 1
W = mg (where w is weight in newton, m is mass and g is acceleration)

W = (25)(9.8)
That means w = 245N
Answer 2

Answer:

Mass =25kg

Explanation:

Given:

Weight on Earth (W)=245N

Acceleration due to gravity on the Earth (g)$$= 9.8\,m/s^2$$

Therefore,

Mass = W /g=(245/9.8)=25kg

Give an example of a negative slope.

Answers

Answer:

A negative slope is a downward slope that descends from left to right. It indicates that as the value of one variable increases, the value of the other variable decreases.

For example, the line y = -2x + 5 has a negative slope of -2. This means that as the value of x increases by 1, the value of y will decrease by 2. Graphically, this line will be a downward slope from left to right.

Newton's law of cooling states that the rate of change of temperature of an object in a surrounding medium is proportional to the difference of the temperature of the medium and the temperature of the object. Suppose a metal bar, initially at temperature 50 degrees Celsius, is placed in a room which is held at the constant temperature of 40 degrees Celsius. One minute later the bar has cooled to 40.18316 degrees . Write the differential equation that models the temperature in the bar (in degrees Celsius) as a function of time (in minutes). Hint: You will need to find the constant of proportionality. Start by calling the constant k and solving the initial value problem to obtain the temperature as a function of k and t . Then use the observed temperature after one minute to solve for k . identify the explicit function for the sequence in the table. x:1, 2, 3, 4, 5, y: 8, 14, 20, 26, 32, Descripcion de Chile Will mark Brainlest ( molecular weight of ammonium sulphate)step by step What is the purpose of exploding the moment"?A.

One approach involved the use of oil-eatingbacteria. However, scientists were divided on its effectiveness. Some maintained that the bacteria were "fairlyfast" in cleaning the spill. Officials reported that the Gulf would make a full recovery by 2012. Yet Samantha Joye,a marine scientist, disagreed. She conducted a study of the sea floor. She found that the bacteria had cleanedonly 10 percent of the oil. She reported that the Gulf would take many years to recover.Do It!The reports wereignoredB conflictinghumorousD appreciated Which reform established by Taft advocated for improving the lives of family, addressing abuse and neglect, and later became part of the Department of Health and Human Services?a) the Childrens Bureaub) the Payne-Aldrich Tariff Actc) the Federal Reserve system d) the food and Drug Administration
