Answer:
There are a few things that have reactions forces in cricket it stars of with the ball bouncing off the grass after being thrown, there is a reaction force from the ground to the ball. The second time there is a reaction force is when the ball makes contact with the bat is providing an equal or greater reaction force to drive the ball. The third force is the force of the ball being caught to your body when the ball is caught there is a reaction force from your hands onto the ball.
Explanation:
For example:
If you drop a cricket ball out of a helicopter hovering 300 m above the ground, it will accelerate up to 123 km/hr in about 5 seconds, having fallen through a distance of about 100 m. It will then fall the remaining 200 m to the ground at 123 km/hr, without gaining any additional speed. At 123 km/hr, the force of gravity pulling the ball down is equal to the drag force of the air pushing it upwards. The total force on the cricket ball is then zero so it falls at a constant speed after the first 100 m."
A ball bowled horizontally at 123 km/hr experiences a backward horizontal drag force that is equal to the weight of the ball. At world record bowling speeds around 160 km/hr, the drag force is 1.7 times greater than the weight of the ball. Regardless of the speed of the ball when it leaves the bowler's hand, air resistance causes the ball to slow down by about 12% by the time it lands on the pitch. It slows down by another 30% or 40% when it hits the pitch, depending on the speed of the pitch and the angle of incidence. A ball bowled at 150 km/hr will arrive 0.46 s later at the batter's end, traveling at about 85 km/hr.

Answer:
true false true true
Explanation:
Please mark me brainliest
What is the density of the substance?
The density of a substance is 0.83 g/mL. We know that the density of water is 1 g/mL. It means the density of the substance is less that that of density of water. If the density of substance is less that water then it will float on water's surface.
Density is how tightly packed particles are in a substance. Warm liquid sinks and cool liquid rises. Heat moves through solid, liquid, and gases through convection currents. Substances with a greater density than water will sink, while substances with less density will float.
Therefore, Density is how tightly packed particles are in a substance. The statement is true.

A. the body can no longer adapt.
B. the body becomes fatigued.
C.the body can perform at a higher level.
D.the hypothalamus releases a hormone.
Answer:
D. the hypothalamus releases a hormone
Explanation:
The first stage is called ¨fight or flight¨ which is triggered by the hormone released.
During the first stage of the stress response, the hypothalamus releases a hormone and the correct option is option D.
The stress response hormone is known as corticotropin-releasing hormone (CRH), which triggers the release of adrenocorticotropic hormone (ACTH) from the pituitary gland. ACTH then stimulates the adrenal glands to release stress hormones such as cortisol, which help the body respond to the stressful situation.
This initial stage is known as the alarm stage, where the body prepares for a fight-or-flight response and activates various physiological and psychological mechanisms to cope with the stressor.
Thus, the ideal selection is option D.
