Some natural hazards are preceded by geologic activities that allow for reliable predictions; other natural hazards occur suddenly, with no notice, and are not yet predictable.
TrueThere are some disasters that can be predicted like tornadoes, tsunamis etc.. But some hazards like earthquake cannot be predicted. Still the technology has not developed so much that it could predict earthquakes...~
Answer:
True
Explanation:
Yes we became modern a lot and are too ahead in terms of technology .We can predict cyclones way before it happens .We can predict tornadoes by measuring air pressure.But we are still unable to predict some hazardous things such as earth quake.A tennis ball has 10 J of energy when it is 1 m above the floor.
Name the store associated with this
energy.
The store associated with the energy when a ball has 10 J of energy when it is 1 m above the floor is gravitational potential energy
What is gravitational potential energy?
Gravitational potential energy is the energy of a body by virtue of its position in the gravitational field.
From the question, If a tennis ball has 10 J of energy when it is 1 m above the floor, first, a work of 10 J was done against gravity to lift the tennis from the floor to a height of 1 m. At the height of 1 m, the work of 10 J is converted to the gravitational potential energy of the tennis ball which is stored in the ball.
Hence, The energy associated when a tennis ball has 10 J of energy and it is 1 m above the floor is gravitational potential energy.

How is thermal equilibrium reached? Question 3 options: When both objects have the same temperature When objects have the same mass When objects are both in the same state of matter (solid, liquid, or gas) When objects have different temperatures.
In the thermal equilibrium, the change in temperature is said to be zero in between the bodies. Thermal equilibrium is reached when both objects have the same temperature.
What is thermal equilibrium?Thermal equilibrium is easily explained by the zeroth law of thermodynamics. If any two-body is at thermal equilibrium there is no change in the temperature of the body.
According to zeroth law if body A is in thermal equilibrium with body B and body B is in thermal equilibrium with C . So body A and C are also in thermal equilibrium.
In the thermal equilibrium, the net heat transfer is said to be zero in between the bodies.
Hence option A IS RIGHT. Thermal equilibrium is reached when both objects have the same temperature

Define force as the cause of acceleration?
Physics
Answer:
In short, a force applied to an object at rest causes it to accelerate in the direction of the force.
Explanation:
Newton's second law says that when a constant force acts on a massive body, it causes it to accelerate, i.e. to change its velocity, at a constant rate.
Answer:
As the force acting upon an object is increased, the acceleration of the object is increased.
Explanation:
The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object.
