Answer:
Hi there! This question is asking to write a Javascript validation function to validate user input. Assuming the input fields have the id set as “phone_number” for the phone input, and “user_name” for the User’s name, we can write the function below to do the validation as required.
Explanation:
function validateForm() {
if isNaN(document.getElementById(“phone_number”).value) {
document.getElementById(“phone_number”).addClass(“error”)
console.log(“Phone number is invalid”)
}
if document.getElementById(“user_name”).length < 11 {
document.getElementById(“user_name”).addClass(“error”)
console.log(“User name is invalid”)
}
document.getElementById(“submit”).addEventListener(“click”, function(e) {
if document.getElementById(“phone_number”).hasClass("error") || document.getElementById(“user_name”).hasClass(“error”) {
e.preventDefault();
}
});
}
Answer:
Prolonged exposure to vibration
Long periods of localized pressure
Explanation:
Repetitive motion is certainly not harmful, but prolonged repetitive motion can be a cause for injury. This is because if you are in repetitive motion for a long time, you exert a lot of force on your body, and that is certainly going to effect your body. And after a certain limit, even death can be a case. Hence, one should be very concerned about the time limit while their body goes through the repetitive motion.
However, neutral position we are always safe, as it’s an ideal position, as in this position, the work done is zero. Work done= force x displacement. And displacement in neutral position is zero. Hence, zero energy is lost. Hence, we are safe in this position.
Hence the above answer.
