It depends on what illness and what country you are in but Mayo Clinic and Johns Hopkins are good sources.

if the 50 kg object slows down to a velocity of 1 m/s how much kinetic energy does it have 100j 50j 25j or none

rodikova [14]

$ek = \frac{1}{2}m {v}^{2}$

$ek = \frac{1}{2}(50) {(1)}^{2}$

$ek = \frac{1}{2}(50)$

$ek = 25j$

I'm not really sure but I do know that it's not 0 because the object is still moving, even if it's only moving at 1 m/s.

A driver fills an 18.9L steel gasoline can with gasoline at 15.0°C right up to the top. He forgets to replace the cap and leaves

GarryVolchara [31]

Answer:

ΔV = 0.98 L

Explanation:

First, we will calculate the increased volume using Charles' Law:

$\frac{V_1}{T_1} = \frac{V_2}{T_2}$

where,

V₁ =initial volume = 18.9 L

V₂ = final volume = ?

T₁ = initial temperature = 15°C + 273 = 288 k

T₂ = final temperature = 30°C + 273 = 303 k

Therefore,

$\frac{18.9\ L}{288\ k} = \frac{V_2}{303\ k}$

V₂ = 19.88 L

Now, we calculate the change in volume:

ΔV = V₂ - V₁ = 19.88L - 18.9 L

ΔV = 0.98 L

This is the volume of gasoline that will spill out.

Find the length of each vector below.

Leona [35]

Answer:

a. 3.6 units

b. 1.4 units

c. 3.6 units

d. 6.1 units

Explanation:

The length of a vector is given by the following formula:

Length = √(x² + y²)

where,

x = x-component of vector

y = y-component of vector

Here,

x = 2

y = 3

Therefore,

Length = √(2² + 3²)

Length = √13

Length = 3.6 units

Here,

x = 1

y = 1

Therefore,

Length = √(1² + 1²)

Length = √2

Length = 1.4 units

Here,

x = 2

y = -3

Therefore,

Length = √(2² + (-3)²)

Length = √13

Length = 3.6 units

Here,

x = 1

y = -6

Therefore,

Length = √(1² + (-6)²)

Length = √37

Length = 6.1 units
