A roller coaster speeds up with constant acceleration for 2.3 s until it reaches a velocity of 35 m/s. During this time, the rol

ler coaster travels 41m. What is the initial velocity of the roller coaster before it begins to accelerate?

Answer:

0.65 m/s

Explanation:

Applying the equation,

v = u + at

35 = u + a×2.3    -(1)

Again, applying the equation,

s = ut + \frac{1}{2}at^{2}

41 = u×2.3 +  \frac{1}{2} × (2.3)^{2}

35.65 = 2u + 2.3a -(2)

comparing first and second we get u= 0.65 m/s

True or false question scientists can predict when an earthquake will occur
Tanya [424]

Answer:

False

Explanation:

Neither the USGS nor any other scientists have ever predicted a major earthquake. USGS scientists can only calculate the probability that a significant earthquake will occur in a specific area within a certain number of years.

1)why do we get electric shock while holding a live wire barefooted and not when wearing rubber shoes?
katrin2010 [14]
Electricity is always going to take the path of least resistance to ground. The rubber in your shoes is not a conductor of electricity, therefore you are not completing the circuit and you don't get shocked. Your bare feet, on the other hand ARE conductors of electricity, so when you hold the wire, you complete the circuit and become the path of least resistance to ground... ZAP!

Find the x-component of this
Sholpan [36]

Answer: 74.8m

Explanation:

We have the vector defined by:

r = 101m

θ = 42.2°

When we want to write this as rectangular components, we have that:

x = r*cos(θ)

y = t*sin(θ)

this is because we can construct a triangle rectangle, where the module of the vector is the hypotenuse, the x component is the adjacent cathetus and the y component is the opposite cathetus.

Then, here we have that the x component is

x = 101m*cos(42.2°) = 74.8m

Mass spectrometer A mass spectrometer is a tool used to determine accurately the mass of individual ionized atoms or molecules,
Oksana_A [137]

Answer:

For carbon 12

ΔV1 = 2265.31 V

ΔV2 = 362.5 V

For carbon 14

ΔV1 = 1941.7 V

ΔV2 = 310.67 V

Explanation:

The complete explanations are given in the attachment below. The formulae for the accelerating potential ΔV1 and ΔV2 are derived and the necessary parameters are substituted into the derived equations.
