The wrench applies greater than 10 N force to the astronaut. The correct option is A.
What is Newton's third law of motion?Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
When the astronaut throws the wrench forward with a force of 10 N, the wrench will apply an equal and opposite force of 10 N to the astronaut in the opposite direction.
Here other options are,
Option B. Less than 10 N is not true because the force applied by the wrench to the astronaut is equal and opposite to the force applied by the astronaut to the wrench, which is 10 N.
Option C. zero; the wrench does not apply a force is not true because the wrench is exerting a force on the astronaut in the opposite direction to the direction in which the wrench is thrown.
Option D. exactly 10 N is not true because the force applied by the wrench to the astronaut is equal and opposite to the force applied by the astronaut to the wrench, which is 10 N, and the two forces act in opposite directions.
Therefore, the force applied by the wrench to the astronaut is greater than 10 N.

Sometimes people refer to Mars as the Red Planet. Because of the rusty iron in the earth, it is red. Mars features weather, polar ice caps, canyons, volcanoes, and seasons just like Earth. Its atmosphere, which is composed of carbon dioxide, nitrogen, and argon, is extremely thin. These define Mars' characteristics.
These are some of the characteristics of the moon, which is the only natural satellite of Earth and the nearest huge celestial body. It is a spherical rocky body that revolves around Earth in a somewhat eccentric orbit at a mean distance of around 384,000 km (238,600 miles), perhaps with a tiny metallic core. It has a 1,738 km (1,080 miles) equatorial radius.
What is planet ?A celestial body inside the Solar System that meets the following criteria is referred to as a "planet": (a) it must be in orbit around the Sun; (b) it must have enough mass to overcome rigid body forces and take on a hydrostatic equilibrium form that is almost circular; and (c) it must have cleared the area in and around its orbit.

What type of device is a coal-fired power plant?
A. A heat pump that uses heat to do work
B. A heat pump that uses work to move heat
C. A heat engine that uses work to move heat
D. A heat engine that uses heat to do work
A coal-fired power plant is a type of heat engine that uses heat to do work. So, the correct option is D.
What is meant by a power plant ?A power plant or power station is defined as a facility designed for producing electrical energy from various other forms of energy.
Here,
A coal-fired power plant is a type of power plant, which is used for the production of electricity by using fuels such as coal, oil, etc.
The coal-fired power plants are the most common type of power station. In these power plants, the main burning materials used are the fossil fuels. The coal is pulverized and then burned into a coal-fired boiler. Then, the boiler water is converted into steam using a heat engine. As a result, this steam is used for the spinning of turbines.
Hence,
A coal-fired power plant is a type of heat engine that uses heat to do work.

A cyclist turns a corner with a radius of 50m at a speed of 10m/s. The cyclist's acceleration is 2 m/s².
What is acceleration?The rate at which an item changes its velocity is known as acceleration, a vector quantity. If an object's velocity is changing, it is acceleration. The net acceleration that objects get as a result of the combined action of gravity and centrifugal force is known as the Earth's gravity, or g. It is a vector quantity whose strength or magnitude is determined by the norm and whose direction correlates with a plumb bob.
a = v²/r
a = (10m/s)² / 50m
a = 2 m/s²
