Itz_Khushi ❣️ 2 years, 10 months ago

A force that does not change the state of rest or motion of an object is a balance force. So a balance force does neither make a body at rest to move nor make a body in motion to come in rest . it does not allow a body in motion to even change its direction or increases its speed too.

Examples ofmetals are gold, silver, copper etc. Examples of non-metals are hydrogen, oxygen, iodine etc. Someelements have intermediate properties between those of metals and non-metals, they are calledmetalloids. A compound is a substance composed of two or more elements, chemically combined withone another in a fixed proportion. The material obtained by the group I is a mixture of the twosubstances. The properties of the mixture are the same as that of its constituents. Q.58) ________ is the only metal that is liquid at room temperature. a. silver b. gold c. copper d. mercury Q.59)The colourless gas with the smell of rotten egg is found in a. group II b. group IV c. group III d. group I Q.60)The constituent of compounds are separated by a. both chemical reaction and electrochemical reaction b. electrochemical reaction c. none of these d. chemical reaction

The given equation is x2+2(m−1)x+(m+5)=0 For the equation to have real and equal roots, the discriminant should be 0. ∴[2(m−1)]2−4(m+5)=0 ⇒4(m2−2m+1)=4(m+5) ⇒m2−3m−4=0 ⇒(m−4)(m+1)=0 ∴m=4 or m=−1
