Answer:1.37
Explanation:
Given
Length of Blade
Let blades be rotating at an angular velocity of
centripetal acceleration at any radial distance r is given by
at
at
thus
Centripetal acceleration depends inversely on the radius. The ratio of the centripetal accelerations at the end of the blade and at 4.78m from the center is approximately 0.73.
The centripetal acceleration of an object moving in a circle of radius r is given by the formula ac = v²/r, where v is the tangential velocity of the object. In this scenario, the velocity at both points on the blade is the same, as the blade is rotating as a whole.
Therefore, the centripetal acceleration on the blade at any point is inversely proportional to the radius from the center of the circle to that point.
So, the ratio of the centripetal acceleration at the end of the blade (6.58 m from the center) to the centripetal acceleration at a point located 4.78 m from the center, is the inverse ratio of their distances from the center. Therefore, the ratio is 4.78/6.58 which approximately equals 0.73.

mass of box =7kg
Explanation:
If the density of ice is 0.92 grams / centimeters³. An ice sculptor orders a one cubic meter block of ice then the mass of the ice block would be 920000 grams.
It can be defined as the mass of any object or body per unit volume of the particular object or body.
As given in the problem If the density of ice is 0.92 grams / centimeters³. An ice sculptor orders a one cubic meter block of ice then the mass of the ice block, then we have to find the mass of the ice block,
1 meter³ = 10⁶ centimeter³
The mass of the ice block = density of the ice × volume of the ice
=0.92 grams / centimeters³×10⁶ centimeter³
=920000 grams
Thus, the mass of the ice block would be 920000 grams or 920 kilograms.
