Answer:

The top of the block has an area of 0.25m².

i) a Calculate the pressure on the top face of the block.

ii) The atmospheric pressure is 1.0 × 10⁵ Pa.

Calculate the pressure on the top face of the block due to the depth h of water.

iii) The density of sea water is 1020kg/m³.

Calculate the depth h.

Answer:

P=F/A, P is for pressure, F is for force, and A is for area, I can't really see half of the picture so I don't know the figures but just substitute them in and rearrange the equation if you have to. Good luck :))

Question 5 At 12:00 pm, a spaceship is at position ⎡⎣324⎤⎦ km ⎣ ⎢ ⎡ ​ 3 2 4 ​ ⎦ ⎥ ⎤ ​ km away from the origin with respect to so
Anettt [7]

Answer:

[1, 6, -2]

Explanation:

Given the following :

Initial Position of spaceship : [3 2 4] km

Velocity of spaceship : [-1 2 - 3] km/hr

Location of ship after two hours have passed :

Distance moved by spaceship :

Velocity × time

[-1 2 -3] × 2 = [-2 4 -6]

Location of ship after two hours :

Initial position + distance moved

[3 2 4] + [-2 4 -6] = [3 + (-2)], [2 + 4], [4 + (-6)]

= [3-2, 2+4, 4-6] = [1, 6, -2]

What is the relationship between an object’s mass and its gravitational potential energy?.
antiseptic1488 [7]

Answer:

If we’re talking about objects on the Earth, the gravitational potential energy is given by:

Explanation:

PEg=mgh

so the energy is proportional to the mass ( m ), but also to the strength of the gravitational field ( g ), and the height ( h ) to which the mass is lifted.
