A) Tolerance

Tolerance is developed after using a drug repeatedly, so the body adapts to it. Because of that, people who develop a tolerance would then need to use more of that drug to get the same effect.

A 2.0 kg wooden block is slid along a concrete surface (μk = 0.21) with an initial speed of 15 m/s. How far will the block slide
exis [7]

Answer:

The distance is 54.6 m

Explanation:

Given that,

Mass = 2.0 kg

Frictional coefficient = 0.21

Initial velocity = 15 m/s

We need to calculate the acceleration

Using formula of frictional force  

F = \mu mg

F=0.21\times2.0\times9.8

F = 4.12\ N

We need to calculate the acceleration

F = ma

a = \dfrac{F}{m}

a =\dfrac{4.12}{2.0}

a=2.06\ m/s^2

We need to calculate the initial velocity

Using equation of motion

v^2=u^2-2as

Put the value  

0=15^2-2\times2.06\times s

s = \dfrac{15^2}{2\times2.06}

s=54.6\ m

Hence, The distance will be 54.6 m.

I need help with two more Physics problems​
sesenic [268]

Answer:

c. They hit at the same time

b. BGS

Explanation:

A marble dropped (initial vertical velocity is 0) will land at the same time as a marble launched horizontally (initial vertical velocity is 0) from the same height.

Boat S has a net speed of 5 m/s (10 − 5).

Boat B has a net speed of 15 m/s (10 + 5).

Boat G has a net speed of ≈11.2 m/s (√(10² + 5²)).

The velocity of the wave involved in the Doppler effect:
Margarita [4]

The Doppler Effect provides the equation for the calculation of apparent frequency:

f=fo[vo/(vo-vr)] 

where:<span>
vo=source wave velocity 
vr=relative speed between source and observer 
f=apparent frequency 
fo=source frequency </span>

<span>
The velocity of the doppler wave is 
v=λf</span>

where λ is light wavelength. Hence,

v=λfo[vo/(vo-vr)] 

Based on the equation, we can say that wave velocity will always be defined by one and only one wavelength.

Therefore the answer is letter C.

Consider the following list of numbers. 129, 685, 125, 511, 601, 52, 46 The height of a binary search tree is the maximum number
NemiM [27]

Answer:

The height of the tree is three (3) deep

Explanation:

It's 3 deep

Under 129, comes 125 and 685;

Under 125, comes 52 : Under 685, comes 511;

Under 52, comes 46 : Under 511, is 601.

This is illustrated below.
