Typical novae occur when (a) a red-giant star ejects a planetary nebula; (b) two neutron stars merge, forming a more massive neu

tron star; (c) an extremely massive star collapses, and also ejects its outer atmosphere; (d) matter accreted from a companion star unstably ignites on the surface of a white dwarf; or (e) a neutron star’s magnetic field becomes strong enough to produce two oppositely directed jets of rapidly moving particles.

How many boxes of potatoes does the Mayflower need if each person gets 3 potatoes a day?
Furkat [3]

Using the appropriate arithmetic operation, the amount of potatoes and cabbage require for the voyage are 19998 and 26664 respectively.

  • <em>Number</em><em> </em><em>of</em><em> </em><em>men</em><em> </em><em>=</em><em> </em><em>47</em>
  • <em>Number</em><em> </em><em>of</em><em> </em><em>women</em><em> </em><em>=</em><em> </em><em>32</em>
  • <em>Number</em><em> </em><em>of</em><em> </em><em>children</em><em> </em><em>=</em><em> </em><em>22</em><em> </em>
  • <em>Number</em><em> </em><em>of</em><em> </em><em>voyage</em><em> </em><em>days</em><em> </em>

Total number of passengers = (47 + 32 + 22) = 101

1.)

If each person gets 3 potatoes per day :

Number of potatoes needed per day = (3×101) = 303

Number of potatoes needed for entire voyage = (303 × 66) = 19998 potatoes.

2.)

If each person gets 4 cabbage per day :

Number of cabbage needed per day = (4×101) = 404

Number of cabbage needed for entire voyage = (404 × 66) = 26664 cabbages.

Hence, the number of cabbage needed for the voyage would be 26664 cabbages.

Alchen [17]
You want the force/area ratio to be the same for both pistons to keep constant pressure. Since 1500/450=3.333, you will need to pick the two sets of dimensions such that (assuming the pistons are rectangular) the product of the pair of dimensions for the 1500 kg piston is 3.333 times the product of the pair of dimensions for the 450 kg piston.

A honeybee with a mass of 0.150 g lands on one end of a floating 4.75-g popsicle stick, as shown in (Figure 1) . After sitting a
Alekssandra [29.7K]

Answer:

0.0443 m/s

Explanation:

m_1 = Mass of honeybee = 0.15 g

m_2 = Mass of popsicle stick = 4.75 g

v_1 = Velocity of honeybee

v_2 = Velocity of stick = 0.14 cm/s

In this system the linear momentum is conserved

m_1v_1=m_2v_2\\\Rightarrow v_1=\dfrac{m_2v_2}{m_1}\\\Rightarrow v_1=\dfrac{4.75\times 0.14}{0.15}\\\Rightarrow v_1=4.43\ m/s

The velocity of the bee is 4.43 cm/s or 0.0443 m/s
