Consider the equation for weight:
W=mg
W is the weight, m is the mass, and g is the acceleration due to gravity.
Therefore, to calculate the weight of an object, just multiply its mass by the acc. due to gravity of the location.
The acc. due to gravity on Earth is approximately 9.81 ms^-2, note that this number may change from place to place, for example, the acc. due to gravity on moon is only 1/6 of Earth's. (Sometimes the question provides g as 10, so make sure you check the instructions before!)
W = 1.5 x 9.81
= 14.715N (≈14.7N)
Therefore, the answer to this question is the last option (or D), 14.7N.
Answer:
pressure and heat is the correct answer
have a nice day! (^o^)
Answer: 
, 
Explanation:
Temperature of the gas is defined as the degree of hotness or coldness of a body. It is expressed in units like 
and 
These units of temperature are inter convertible.
We are given:
Temperature of the gas = 
Converting this unit of temperature into by using conversion factor:
Converting this unit of temperature into by using conversion factor:
Thus the temperature on the Celsius and Kelvin scales are and respectively.
Answer:
the correct answer is option C. Na
The bonds in the SiCl₄ molecules will be more polar.
The polarity of bonds within a molecule depends on the difference in electronegativity of the atoms that are involved in the bond. Chlorine is a more electronegative atom than iodine. Therefore, the electrons in the Si-Cl bond will be more concentrated near the Cl, creating polarity in the bond. Iodine is not as electronegative, so it will not result in a very polarized Si-I bond
