Answer:
The distance traveled by the ball before it lands in the other player's glove is 130.96 m.
Explanation:
Given;
angle of projection of the ball, θ = 40⁰
initial velocity of the ball, u = 36.1 m/s
The distance traveled by the ball before it lands in the other player's glove is the range of the projectile, calculated as follows;
Therefore, the distance traveled by the ball before it lands in the other player's glove is 130.96 m.
Answer:
Option C or the third option.
Explanation: Water is a renewable resource there is so much of it and it just keeps circulating through the system it doesn't run out.
Diffraction patterns are due to interference<span>. Diffraction is a phenomena which occurs when a wave encounters an obstacle. It is the bending of light around the corners if the obstacle.</span>
Answer:
b. The final temperature of the coffee cup will be higher than 25°C but less than 75°C.
Explanation:
We know in thermal equilibrium.
Heat loss by one object = Heat gain by other object.
Now, heat is loss by the object whose temperature is higher than other because heat travels from high temperature to other.
And the object who gain heat its temperature increases till both body reach same temperature.
In this case, water loss heat, therefore its temperature decreases.
Similarly , metal block is at low temperature so its temperature increases.
Therefore , both water and metal block must have temperature less than and to have thermal equilibrium.
Hand grip test an example of an isometric muscle contraction.
Isometric(increased pressure but no shortening)
Explanation:
- Isometric contraction, is one in which the muscle is activated, but instead of being allowed to lengthen or shorten, it is held at a constant length.
- An isometric exercise is a form of exercise involving the static contraction of a muscle without any visible movement in the angle of the joint.
- Isometric exercises are contractions of a particular muscle or group of muscles. During isometric exercises, the muscle doesn't noticeably change length and the affected joint doesn't move. Isometric exercises help maintain strength. They can also build strength, but not effectively.
- Isometric exercise is also known as static strength training. (Examples include the plank and side bridge as well as the wall sit and many yoga poses such as chair and tree poses).
