A baseball player throws the ball to first base to make an out consider the forces acting only on the ball when is the ball is in the hand of the player

choose all that apply

Gravity , Spring , Tension , Normal , friction , air resistance , Apply Force

The forces acting on the ball when is the ball is in the hand of the player is the force due to gravity and the normal force.

Explanation:

1. The force due to the gravity:

Yes, baseball relates to gravity. when a player throws the ball then the ball will be launched in the air

without the gravity they ball will not come back to the ground again.Due to the gravity, the ball will fall down

2. Normal forces:

When a baseball is thrown or struck, Newton's laws of motion determines the subsequent movement. Based

on the law, the ball will be still the motion until there is an external force acting on it.

hi there if you are asking for conformation that wavelingth is the correct answer is wrong it is the answer is frequency. : )

i hope this you out, have a wonderful day

answer: the correct answer is 1.

explanation: there are various process in which a radioactive nuclei decays:

1) alpha decay: in this process, a heavier nuclei decays into lighter nuclei by releasing alpha particle. the mass number is reduced by 4 units.

2) electron capture: in this decay process, a parent nuclei absorbs an electron and gets converted into a neutron. simply, a proton and an electron combines together to form a neutron. mass number does not change in this process.

3) gamma ray emission: it is a decay process in which an unstable nuclei gives excess energy by a spontaneous electromagnetic process. this decay releases . this process does not change the mass number.

4) positron emission: it is a type of decay process, in which a proton gets converted to neutron and an electron neutrino. this is also known as -decay. in this the mass number remains same.

from the above information, we see that only alpha-decay is producing a change in the mass number of the nucleus.
