An athlete whirls a 7.00 kg hammer 1.8 m from the axis of rotation in a horizontal circle, as
iogann1982 [59]

Answer:

A-500 N

Explanation:

The computation of the tension in the chain is shown below

As we know that

F = ma

where

F denotes force

m denotes mass = 7

And, a denotes acceleration

Now for the acceleration we have to do the following calculations

The speed (v) of the hammer is

v = Angular speed × radius

where,

Angular seed = 2 × π ÷ Time Period

So, v = 2 × π × r ÷ P

v = 2 × 3.14 × 1.8 ÷ 1

= 11.304 m/s

Now

a = v^2 ÷ r

= 70.98912 m/s^2

Now the tension is  

T = F = m × a

= 7 × 70.98912

= 496.92384 N

= 500 N

A capacitor consists of two square plates, 8.7 cm on a side, separated by a 2.0 mm air gap. How much energy would be stored in t
slavikrds [6]

Answer:

122.84 J

Explanation:

Since plate is square, area, A is given by (8.7/100)^{2}=0.007569m^{2}

The distance between plates, d, is given in the question as 2mm=0.002m

Charge on plate, Q, as given in the question is 240 \mu c

Assuming mica dielectric constant, k of 7

Capacitance, C is given by

C=\frac {k\epsilon_{o}A}{d}=\frac {(7)(8.85*10^{-12})(0.007569)}{0.002}=2.34*10*^{-10}F

Stored energy, E is given by

E=\frac {Q^{2}}{2C}=\frac {(240*10^{-6})^{2}}{2*(2.34*10^{-10})}=122.84J

Therefore, the stored energy is 122.84 J

The fundamental resolution of a lens or telescope is determined by:
Sliva [168]

Answer:

The numerical aperture of the lens.

Explanation:

A numerical aperture is a dimensionless number that is the range of angles that the system can accept / emit light.

Jogging on hard surfaces with insufficiently padded shoes produces large forces in the feet and legs.
Step2247 [10]

Answer:

Part a)

F = 15600 N

Part b)

force is 21.2 times more than the weight of the person

Explanation:

Part a)

As it is given that the distance after which he stopped is given as

d = 1.50 cm

here finally it stops so final speed is given as

v_f = 0

initial speed is given as

v_i = 6 m/s

now by the equation of kinematics we know that

v_f^2 - v_i^2 = 2a d

0^2 - 6^2 = 2(a)(0.015)

a = -1200 m/s^2

Now the force on the leg is given as

F = ma

m = mass of leg = 13 kg

F = (13 kg)(-1200 m/s^2)

F = 15600 N

Part b)

Force due to weight of the object

F_g = Mg

here we know

M = 75.0 kg

F_g = 75(9.81)

F_g = 735.75 N

Now we know that the ratio of the weight with the force on leg is given as

\frac{F}{F_g} = \frac{15600}{735.75} = 21.2 N

so force is 21.2 times more than the weight of the person
