Explanation:

The most established layers are on the base, and the most youthful layers are on the top. Since dregs here and there incorporate once-living creatures, sedimentary stone regularly contains a great deal of fossils. Fossils are once living beings that have been transformed into rock, fit as a fiddle or type of the creature can in any case be seen.

the maximum normal force a pilot can withstand is about eight times his weight. What is the maximum radius of curvature that a j

neonofarm [45]

Complete Question

the maximum force a pilot can stand is about seven times his weight. what is the minimum radius of curvature that a jet plane's pilot, pulling out of a vertical dive, can tolerate at a speed of 250m/s?

Answer:

The value is $r = \frac{250^2 }{6 * 9.8 }$

Explanation:

From the question we are told that

The weight of the pilot is $W = mg$

The maximum force a pilot can withstand is $F_{max} = 7 W = 7 (mg)$

The speed is $v = 250 \ m/s$

Generally the centripetal force acting on the pilot is equal to the net force acting on the pilot i.e

$F_c = F_{max} - mg$

Here N is the normal force acting on the pilot

Now

$F_c = \frac{m v^2 }{r}$

$\frac{m v^2 }{r} = 7(mg) - mg$

=> $r = \frac{v^2 }{6g}$

=> $r = \frac{250^2 }{6 * 9.8 }$

=> $r = 1063 \ m$

A cup of tea at room temperature of 24°C is heated until it has twice the internal energy. Calculate the final temperature of th

elena-s [515]

The final temperature of the tea cup is 100°C.

<h3>What is internal energy?</h3>

The Internal energy is the energy of a substance due to to the constant random motion of its particles.

The symbol for internal energy of a substance is U and it is measured in Joules.

ΔU = q + W

q is the heat, q = mcΔT

W is the mechanical work.

In conclusion, the final temperature of the tea cup at room temperature of 24 °C which is heated until it has twice the internal energy is 100°C.

<h3>Simple pendulum</h3>

The simple pendulum a system that moves in an oscillatory motion. It consist of a suspended mass on a string with length placed on a fixed support.

The acceleration due to gravity can be measured using a simple pendulum. During this experiment:

The fan should be switched off to prevent air resistance
The stopwatch zero error should be noted and corrected
The angle of bob displacement should be small

A rock is thrown upward with an initial velocity of 9.6m/s to what hight does it rise and how long does it take to reach that hi

Lera25 [3.4K]

Given:

u(initial velocity):9.6 m/s

at the maximum height final velocity =0

The acceleration acting on the body is gravity as it is free falling object

=-9.8m/s^2

Now we know that

v^2-u^2 = 2as

Where v is the final velocity measured in m/s

u is the initial velocity which is measured in m/s

a is the acceleration measured in m/s^2

s is the distance traveled by the rock in this case it is considered as the height

Substituting these values we get

0-9.6= 2 x -9.8 x s

s= 0.49 m

Consider t as the time taken for the rock to travel

v=u+at

0=9.6 -9.8t

t=0.98sec
