Answer:
Vx = 6 m / s and .vy = 7 m / s
Explanation:
a) Let's substitute the value of time in the equations
x (1) = a +6
y (1) = b + 7
b) and e) We calculate the position for t = 2 s
x (2) = a +12
y (2) = b +14
We calculate the average speed
v = (x (2) -x (1)) / t2- t1
vₓ = ((a + 12) - (a-6)) / (2-1)
vₓ = 6 m / s
= ((b + 14) - (b-7)) / 1
= 7 m / s
c) and f) The instantaneous bone change calculates with the derivative
vₓ = dx / dt
vₓ = 6 m / s
That is constant for all time
= dy / dt
= 7 m / s
d) The speed on the x-axis is constant and is worth vx = 6 m / s
Answer: Yes,graded receptor potential always depolarize.
Yes,graded receptor potentials must occur to depolarize the neutrons to threshold before action potentials can occur.
Explanation:
Answer:
h = 1.8 m
Explanation:
The initial velocity of the glove, u =- 6 m/s
We need to find the maximum height of the glove. Let it is equal to h. Using equation of kinematics. At the maximum height v = 0
, h is the maximum height and a = -g

Hence, it will go up to a height of 1.8 m.
Correct answer choice is :
B) Petroleum
Explanation:
Petroleum is commonly happening, yellow to the black liquid obtained in geological structures below the Earth's surface. It is usually filtered into different types of fuels. Petroleum outcomes involve transport fuels, fuel oils for heating and power generation, pavement and road oil, and feedstocks for making the compounds, plastics, and plastic elements that are in almost everything we use.
Answer:
The position is
relative to the base of the ocean
Explanation:
From the question we are told that
The angle made by the incline with the horizontal is 
The constant acceleration is 
The distance covered is 
The height of the cliff is 
The velocity of the car is mathematically represented as

The initial velocity of the car is u= 0
So

substituting values


The vertical component of this velocity is

substituting values


The negative sign is because is moving in the negative direction of the y-axis
The horizontal component of this velocity is



Now according to equation of motion we have

substituting values

using quadratic equation we have that

given that time cannot be negative

The car’s position relative to the base of the cliff when the car lands in the ocean is mathematically evaluate as

substituting values
