A 65.0-kg woman steps off a 10.0-m diving platform and drops straight down into the water. 1) If she reaches a depth of 3.40 m,
babymother [125]

Answer:

19372.29 N

Explanation:

Kinetic Energy of the man = Work done by the average resistive force of water.

mg(H+d) = F×d............................ Equation 1

where, m = mass of the woman, H = Height of the platform, d = depth of water reached, F = average resistive force exerted by water.

make F the subject of the equation,

F = mg(H+d)/d...................... Equation 2

Given: m = 65.0 kg, H = 10 m, d = 3.4 m, g = 9.8 m/s²

Substitute into equation 2

F = 65(9.8)(100+3.4)/3.4

F = 19372.29 N

Give reasons with examples why houses are made up of bricks and cement instead of metal
tatyana61 [14]

Answer:

The most important is that the thermal conductivity of the armadillas several orders of magnitude lower than the thermal conductivity of the metal, therefore it is easier to maintain the temperature in winter

Explanation:

Cement and bricks are used in the construction of houses instead of metal, for several reasons

* The most important is that the thermal conductivity of the armadillas several orders of magnitude lower than the thermal conductivity of the metal, therefore it is easier to maintain the temperature in winter

* Metal has more oxidation problems than brick

* The cost of sheet metal is higher than the cost of cement brick.

Please help!! answer as many questions as you know please <3
IRISSAK [1]

Answer: (1) centripetal force is inversely proportional to the radius of an object moving in a circular form.

Centripetal force = mv^{2}/r.

m=mass, v=velocity, r=radius.

(2). Doubling the mass affect the centripetal force following the fact that the centripetal force is directly proportional to the mass therefore, if the centripetal force increases four times (Radius kept constant), the mass increases two times.

(3) If radius is increased, then the centripetal force will decrease.

(4).  If mass is doubled, then the centripetal force will also double.

Explanation:

from the above relation, centripetal force is inversely proportional to the radius and is directly proportional to the mass and velocity.

If only the centripetal force is increase and others are kept as it is, then the moving object will gradually move towards the focus point reducing the radius proportional to the increase in centripetal force.

for example:- relating to mass and velocity, if the centripetal force is increase four times, the mass or velocity will increase two times keeping the radius constant for the condition.

Sarah cycles 30 miles to her grandmother’s house at a steady speed of 10 mph. If she leaves home at 2:00 pm, what time will she
AfilCa [17]

Answer:

5:00p.m

She is traveling 30 miles and moves 10 miles for each hour therefore 30/10=3

This means she cycled for 3 hours adding this to our time we then have 5p.m
