Why was Thompson's Plum pudding model a significant departure from previous models?
PSYCHO15rus [73]

Answer:

Thomson's cathode-ray tube experiments led him to develop the plum-pudding model, which stated that each atom had positively charged particles spread throughout its negatively charged matter. Reword the statement so it is true. ... More alpha particles were deflected than he expected.

Explanation:

Well.. I hope it helps you..

Just correct me if I'm wrong..

Which component of physical fitness is skill related a) flexibility, b) cardio respiratory endurance, c) muscular strength, d) a
WARRIOR [948]

Answer:

d) Agility

Explanation:

Agility is defined as the capability or ability of the body to change the position of the body efficiently, and it requires the isolated movement's integration skills by using a combination of speed, balance, reflexes, coordination, strength, and endurance.

In the field of sport, it is categorized in a unique sport because it is a combination of various factors.

Therefore, agility is a component that is related to skill-related physical fitness.

A cardiac defibrillator stores 1275 J of energy when it is charged to 5.6kV What is the capacitance? O 11.3 pF 96.1 pF O 813 F
Angelina_Jolie [31]

Answer: 813.13(10)^{-7}F

Explanation:

The answer is not among the given options. However, this is a good example of the relation between the energy stored in a capacitor Wand its capacitance C, which is given by the following equation:

W=\frac{1}{2}CV^{2}   (1)

Where:

W=1275J

V=5.6kV=5.6(10)^{3}V is the voltage

C is the capacitance in Farads, the value we want to find

Isolating C from (1):

C=\frac{2W}{V^{2}}   (2)

C=\frac{2(1275J)}{(5.6(10)^{3}V)^{2}}   (3)

Finally:

C=0.000081313F=813.13(10)^{-7}F This is the capacitance of the cardiac defibrillator

Consider a 200-ft-high, 1200-ft-wide dam filled to capacity. Determine (a) the hydrostatic force on the dam and (b) the force pe
Allisa [31]

Answer:

a)  F_g=1.5*10^9Ibf

b)  F_t=12490Ibf/ft^2

     F_b=0

Explanation:

From the question we are told that:

Height h=200ft

Width w=1200ft

a)

Generally the equation for Dam's Hydro static force is mathematically given by

F_g=\rho*g*\frac{h}{2}(w*h)

Where

\rho=Density\ of\ water

\rho=62.4Ibm/ft^3

Therefore

F_g=62.4*32.2*\frac{200}{2}(1200*200)

F_g=1.5*10^9Ibf

b)

Generally the equation for Dam's Force per unit area is mathematically given by

F=\rho*g*h

For Top

F_t=\rho*g*h

F_t=62.4*32.2*200

F_t=12490Ibf/ft^2

For bottom

Here \\H=0 zero

Therefore

F_b=0
