Answer:

Independent Variable: Watching cartoon alone or with others

Dependent Variable: how funny they found the cartoon to be

Explanation:

A dependent variable is the variable being tested. The change in the value of dependent variable depends on the independent variable.

An independent variable is used to test the effects on dependent variable and its does not depend on any variable.

In the above example the dependent variable is how funny the cartoon was. This is being tested and it is tested by independent variable i.e. Students watching cartoon either alone or with others. So the cartoon is funny or not depends on watching cartoon alone or with friends.

A tiger leaps with a horizontal speed of 4.5 m/s from a boulder and lands 15 meters away.What is the vertical velocity with whic
Gelneren [198K]

Answer:

v_oy = 16.33 m/s

Explanation:

To find the vertical velocity of the tiger, you use the information about the horizontal velocity and maximum horizontal distance traveled.

You use the following formula for the range of the trajectory:

x_{max}=\frac{2v_{ox}v_{oy}}{g}     ( 1 )

v_ox: horizontal initial velocity = 4.5m/s

v_oy: vertical initial velocity = ?

g: gravitational acceleration = 9.8m/s^2

x_max: range of the trajectory = 15 m

You do v_oy the subject of the formula ( 1 ) and you replace the values of the other parameters in order to calculate v_oy:

v_{oy}=\frac{gx_{max}}{2v_{ox}}=\frac{(9.8m/s^2)(15m)}{2(4.5m/s)}\\\\v_{oy}=16.33\frac{m}{s}

hence, the initial vertical velocity of the tiger is 16.33m/s

Ket [755]
  • Height=h=21m
  • Mass=m=12kg

\\ \rm\longmapsto P.E=mgh

\\ \rm\longmapsto P.E=12(10)(21)

\\ \rm\longmapsto P.E=120(21)

\\ \rm\longmapsto P.E=2520J

leonid [27]

Answer:

 the bending moment will be W from either sides

Explanation:

bending moment= force (load) * perpendicular distance, if I understand the question the distance will be 1/2 of the length

=> f x 1/2(l) =W*1/2(2) =W
