Which statement about ocean surface currents is false?
Alla [95]

A) they have no effect on air temperature over land on the coast is False

Explanation:

  • warm and cold ocean currents can influence the coastal areas only when the air is blown into the land from the sea.
  • the temperature over the land increases when warm ocean currents heat the air above the ocean.
  • the temperature over the land decreases when cold ocean currents cool the air above the ocean and can bring colder winds to the coastal regions.
  • so, ocean currents play a major role in regulating the air temperature over land on the coastal region.

A gazelle leaps from a cliff 2.5 m high with a speed of 5.6m/s.
jeyben [28]

Initial speed of Gazelle is along x direction and its value will be

v_x = 5.6 m/s

also its initial height is given as

y = 2.5 m

Part a)

now from kinematics along Y direction

\Delta y = v_y t + \frac{1}{2} at^2

as we know that

\Delta y = 0

v_y = 0

a = 9.8 m/s^2

2.5 = 0 + \frac{1}{2} (9.8) t^2

t = 0.714 s

Part b)

distance moved horizontally

\Delta x = v_x t

as we know that

v_x = 5.6 m/s

now we will have

v_x = 5.6 (0.714) = 4m

so it will lend at distance of 4 m.

Part c)

final velocity in vertical direction

v_{fy} = v_y + at

v_{fy} = 0 + (9.8)(0.714) = 7 m/s

v_x = 5.6 m/s

so net speed will be

v^2 = v_x^2 + v_y^2

v^2 = 7^2 + 5.6^2

v = 8.96 m/s

you can use a torque feeler that consists of a meterstick held at the 0 cm end with a weight dangling from various positions alo
Deffense [45]

Answer:

T=7.3575\ N.m

Explanation:

Given:

length of the stick, l=100\ cm=1\ m

position of holding the stick that acts as a hinge, f=0\ cm

mass of the object, m=1\ kg

position of hanging the mass on the meter stick, x=50\ cm=0.5\ m

new position of hanging the mass, x'=75\ cm=0.75\ m

<u>Now the torque in the initial position:</u>

T=mg.x

where:

g= acceleration due to gravity

T=1\times 9.81\times 0.5

T=4.905\ N.m

Now when the mass is at the new position:

T=mg.x'

T=1\times 9.81\times 0.75

T=7.3575\ N.m

What is/are the external cause code(s) for a passenger involved in a mva that lost control on the highway and hits a guardrail?
Sholpan [36]
Here is the answer. The external cause code for a passenger that is involved in a MVA that lost control on the highway and hits a guardrail is E815. Your fifth digit is a 1 for a motor vehicle passenger. You would use an additional E code when a place of occurrence (example, home or parking lot) is documented. In this case, the location is documented as the highway. Hope this helps.
