Answer:
Mechanical energy = 145 Joules
Explanation:
Given the following data;
Kinetic energy = 115J
Gravitational Potential energy = 30J
To find the mechanical energy;
Mechanical energy = kinetic energy + gravitational potential energy
Substituting into the equation, we have
Mechanical energy = 115 + 30
Mechanical energy = 145 Joules.
Mechanical energy can be defined as the ability (capacity) to do work. The two (2) main types of mechanical energy are;
a. Gravitational potential energy (GPE): it is an energy possessed by an object or body due to its position above the earth.
b. Kinetic energy (KE): it is an energy possessed by an object or body due to its motion.
Which process is responsible for causing rock to rise in a convection current?
Answer:
Seafloor spreading.
Explanation:
Seafloor spreading is a process that is responsible for causing rock to rise in a convection current. Convection currents moves the Earth's rigid tectonic plates in the planet's fluid molten mantle. Seafloor spreading is a process in which tectonic plates split apart from each other. As the movement of tectonic plates from each other occurs, heat released from the mantle's convection currents makes the crust more plastic and less dense.
Answer these questions
Define natural hazard ?
What is the difference between tectonic hazards and weather hazards ?
why do convection currents in the mantle occur?
Its geography sorry!I pressed the wrong thing
Explanation:
Natural hazard: an extreme event that can cause extreme damage to property, disrupt human activities and cause loss of life e.g. flooding.
Tectonic hazards basically happen when the earths crust moves. For example when the plates move there's friction which can cause them to become stuck and tension builds until the plates release, this leads to an earthquake. weather hazards happen when a regain has certain weather conditions like really heavy rain fall can lead to flooding.
convection currents occur because there's heat rising and falling inside the mantle.
Hope this helps!

If there are more people living in an area or a certain type of area, it is more likely that more people will be affected by a
Answer:
Natural disaster.
Explanation:
A natural disaster can be defined as a natural occurrence beyond human control and it is typically characterized by injuries, death or damage to both the living and non-living organisms such as humans, animals, plants or properties staying within the environment. Therefore, a natural disaster is capable of endangering the lives of the people living in a susceptible area, as well as causing damages to buildings, cars, trees, etc.
Some examples of natural disaster are earthquake, tornado, flood, wildfire, volcano, etc.
The higher the number of people and properties in an area prone to natural disasters, the higher (greater) would be its impact.
Hence, if there are more people living in an area or a certain type of area, it is more likely that more people will be affected by a natural disaster.
Which of the following is an example of how plants
have adapted to the tropical rainforest?
1
Lianas are able to attach
themselves to trees and climb
towards the sunlight
2
Every autumn plants and trees
lose their leaves
3
Ferns are able to curl up and
protect themselves from the
frost
4
Plants gobble up anything in
sight in order to get their
nutrients
1st one is the answer.. Lianas ,they are tall and thin so they can easily climb towards the sunlight
Answer:
1 is the answer, lianas attach themselves to tree and climb to get sunlight
