Lower. Water expands on lower temperatures, meaning less molecules in 1 m3, thus making it less dense
Answer:
1 cm3 is = 1 ml. Therefore 1000 g of seawater = 973.71 mL.
Explanation:
Seawater salinity will vary from place to place and with the temperature of the seawater. Of course the composition of dissolved substances in seawater, along with salt that is, will also vary from place to place.
On average, seawater in the world's oceans has a salinity of approximately 3.5%, or 35 parts per thousand. This means that for every 1 litre (1000 mL) of seawater, there are 35 grams of salts (mostly, but not entirely, sodium chloride) dissolved in it.
Seawater has an average density of 1.027 g/cm3, but this varies with temperature and salinity over a range of about 1.020 to 1.029.
Answer:
option E.
Explanation:
When the ball is at the highest point the velocity of the ball is zero.
At the height point the kinetic energy is zero and potential energy is maximum.
At maximum point momentum cannot be maximum because velocity is zero.
Acceleration on the ball is equal to acceleration due to gravity on the ball.
Hence, the correct answer is option E.

Please give me brainly,
The thermal energy of an object depends on three things: 4 the number of molecules in the object 4 the temperature of the object (average molecular motion) 4 the arrangement of the object's molecules (states of matter). The more molecules an object has at a given temperature, the more thermal energy it has.
Force=mass*acceleration
F=ma
F=25*5
F=100 N
