Answer:
b) d = 0.71 Km
Explanation:
Car kinematics
Car 1 moves with uniformly accelerated movement
Formula (1)
d: displacement in meters (m)
v₀: initial speed in m/s
vf: final speed in m/s
a: acceleration in m/s²
Equivalences:
1mile = 1609.34 meters
1 hour = 3600s
1km = 1000m
Known data
a = -0.5 m/s²
Distance calculation
We replace data in the Formula (1)
Answer:
option b
Explanation:
the heavier one will have twice the kinetic energy of the lighter one
Answer:
Explanation:
potential energy of water is converted into heat energy
P E = mgh = m x 9.8 x 111
= 1087.8 m .
Let rise in temperature θ
m x s x θ = heat absorbed
m x s x θ = 1087.8 m
m x 4182 x θ = 1087.8 m
θ = 0.26 degree celsius .
Answer:
The probability for the proportion of apples with diameters less than 3.5 inches is 0.1056.
Explanation:
For a normal distribution, z score is calculated using this formula: (X-μ)/σx
Where Mean, μ = 4
Standard deviation, σ = 0.400
The probability for the proportion of apples with diameters less than 3.5 inches is expressed below:
Probability = P(X<3.5)
= P(Z<-1.25)
Probability = 0.1056
