At an instant when a 4.0-kg object has an acceleration equal to (5i + 3j) m/s2, one of the two forces acting on the object is known to be (12i + 22j) N. Determine the magnitude of the other force acting on the object.1) 2.0 N2) 13 N3) 18 N4) 1.7 N5) 20 N The […]

Change 7/10 pi radians to degree measure The Correct Answer and Explanation is: To convert ( \frac{7}{10} \pi ) radians to degrees, you need to use the conversion factor between radians and degrees. The relationship between radians and degrees is based on the fact that a full circle is 360 degrees, which is equivalent to

What is the age in years of a bone in which the 14C/12C ratio is measured to be 4.45×10-132 Express your answer as a number of years. The Correct Answer and Explanation is: To determine the age of the bone, we use the concept of radiocarbon dating, which relies on the decay of carbon-14 ((^{14}C))

What is the fractional form of 0.8 repeating The Correct Answer and Explanation is: To convert the repeating decimal ( 0.\overline{8} ) (where the 8 repeats infinitely) into a fraction, we follow a systematic algebraic approach. Let’s go through the steps in detail: Step 1: Represent the Repeating Decimal as a Variable Let ( x

A constant force of 8N acting on an object displaces it through a distance of 3.0 m in the direction of force. Calculate work-done by the force on the object.​ The Correct Answer and Explanation is: To calculate the work done by the force on the object, we can use the formula for work: [\text{Work}
