Answer:
Explanation:
Given
Initial Form: Onyx
Final Form: Rectangular Solid
Dimension of Solid = 5.10 cm by 5.10 cm by 2.50 mm
Required
Volume of the solid (in cm³)
The volume of a solid is calculated as thus;
Assume the following;
The first thing to do is to convert the assumed height from mm to cm
Given that;
This implies that
Hence, the dimension of the solid in cm is:
The Volume is then calculated as;
Hence, the volume of the rectangular solid is
Answer: An applied force of 50 N is used to accelerate an object to the right across. A 5-kg object is sliding to the right and encountering a friction force that slows it down. Explanation: m=1000 kg and a=3m/s2 . hence, the force needed to accelerate the 1000kg car by 3m/s2 is 3000N

Answer:
a) 65.74 = 4 significant figures
b) 60.009 = 5 significant figures
c) 66_ = 2 significant figures
d) 65.750 = 5 significant figures
Explanation:
Significant figures or digits is defined as the total number of digits in a number that have meaning and contribute to the precision of the given number.
a) 65.74 = 4 significant figures, all the non-zero figures are considered significant.
b) 60.009 = 5 significant figures, zeros present between non-zero figures are significant.
c) 66_ = 2 significant figures, all the non-zero figures are considered significant.
d) 65.750 = 5 significant figures, all the non-zero figures and the trailing zero after the decimal are significant.
