<h3><u>Answer;</u></h3>
Higher temperatures
A wave will go faster through a liquid at <em><u>highe</u></em><u>r </u>temperatures
<h3><u>Explanation;</u></h3>
- <em><u>Mechanical waves are types of waves that require a material medium for transmission.</u></em> An example of mechanical wave is the sound wave whose transmission occurs in medium such as solids, liquids and gases.
- <em><u>The transmission of mechanical waves involves vibration of particles through the medium of transmission, thus transfer of energy from one point to another. </u></em>The vibration of particle may be in the form of a longitudinal wave or a transverse wave.
- <em><u>Increasing the temperature in a medium increases the kinetic energy of the particles in the medium and thus increasing the speed at which the particles vibrates and thus aiding a faster transmission of a wave.</u></em>
Oceanic crust is being formed it is because of the tectonic plates. Tectonic plates work because of volcanic eruption every time it will erupt the tectonic plates underground will have more pressure on magma, then below there will be a volcano thats why their is a volcano in ocean. The heat rises up then it will open, thats what we call divergent bounderies then their will be earthquakes form. Then another plate opens up and the crust is going down, it will stop if the volcano stops erupting because there is more lava left in volcano then it will go underwater and thats why oceanic crust is being formed.

Specific heat capacity= heat energy/mass×temperature rise
962°C - 20°C = 942K
Heat energy (Eh) = 239 × 1.55 × 942
Eh= 348963.9J
shc of Ag: 238.6 J/kg-K
m of Ag: 1.55kg
Answer:
1. 23°
2. 65°
Explanation:
1.
The law of reflection provides that for the same medium, the angle of reflection equals the angle of incidence.
Similarly, here, angle of incidence and reflection will be 46°÷2=23°
2. Since the normal, angles of reflection and incidence lie on the same plane and also the angles of reflection and incidence are equal then the angle between the plane of the mirror and the reflected beam will be given by 90-25=65°
Answer:
The change in angular momentum is 
Explanation:
From the question we are told that
The initial angular velocity of the spinning top is 
The angular velocity after it slow down is 
The time for it to slow down is 
The rotational inertia due to friction is 
Generally the change in the angular momentum is mathematically represented as
substituting values
