Answer:
C
Explanation:
Given that a line starts at the origin ( 0, 0) and ends at (5, 20)
Where
V1 = 0
V2 = 20
T1 =0
T2 = 5
The slope or gradient of a velocity time graph is the acceleration.
Slope = change in V/ change in t
That is,
Slope = ( V2 - V1 )/ ( T2 - T1 )
Substitutes all the values into the formula
Slope = ( 20 - 0 )/( 5 - 0 )
Slope = 20/5
Slope = 4 m/s^2
Therefore, acceleration of the object is 4m/s^2
Answer:
656.09rad
Explanation:
We start from the equation of time based on the acceleration that says the following
We have this values practically,
Substituting,
Angular velocity is given by,
Answer:
A is benthos
B is Nekton
Explanation:
I looked ip up lol
According to the internet:
Nekton are free-swimming animals that can move throughout the water column. Squid, most fishes, and marine mammals such as whales and seals are nekton. Benthos are organisms that inhabit the ocean floor. Some benthos, like crabs, sea stars, octopus, and lobsters, move from place to place.
Hope i helped!
Answer:
Walking,horse pulling the cart, firing of a gun
Explanation:
when we walk we exert force on earth, earth exerts equal force of us
horse applys force in in opposite direction on earth,earth applys equal force and it pulls the cart
when we fire a gun,it apply equal force of us.It is called recoil velocity of a gun
Answer: The partial pressure of if the total pressure of the mixture is 3.9 atm is 0.975 atm
Explanation:
According to Raoult's law, the vapor pressure of a component at a given temperature is equal to the mole fraction of that component multiplied by the vapor pressure of that component in the pure state.
where, x = mole fraction of nitrogen in solution = 0.25
= partial pressure of nitrogen = ?
= Total pressure = 3.9 atm
Putting in the values :
The partial pressure of is 0.975 atm
